Bachelor’s Thesis in Physics

The Bachelor’s Thesis outcome of an independent research project completes the study program.

Bachelorarbeit und Kolloquium sind im Studienplan während des 6. Fachsemesters vorgesehen. Da der Gesamtumfang mit 15 CP etwa 12 Wochen in Vollzeit entspricht, muss die Arbeit in der Regel teilweise in Teilzeit während der Vorlesungen erfolgen. Das Konzept der mit doppelter Wochenstundenzahl dafür aber nur bis zur Mitte des Semesters gelesenen intensiven Lehrveranstaltungen in den Expert-Modulen im 6. Fachsemester schafft allerdings ausreichenden Freiraum in der zweiten Semesterhälfte, um die Bachelorarbeit fertig zu stellen.

	2D optomechanics (Thema ist bereits vergeben)	Poot
	Arbeitsgruppe Quantentechnologien Beschreibung Optomechanics is an extremely exciting field where the tiniest motions of mechanical resonators are measured with the help of laser light. So far, most of these experiments have been done with beams and cantilevers, in other words with one-dimensional structures. In the Quantum Technologies Lab we have just build a new setup, where we can measure the vibrations of 2D mechanical systems. The goal of this project is to explore the world of 2D optomechanics. For this, we have two kinds of samples in mind: one is made from silicon nitride, which is a material with extremely high quality factors. This material is not only used in the manufacturing process of chips, but is also a great material to do optomechanics with. The other direction is to use materials that are just a few atoms thick: This includes graphene, boron nitride, and sandwiches of these true 2D materials. For this, we collaborate with the Karlsruhe Institute of Technology. We will make the samples for you in the cleanroom, and it will be your goal to measure them with our new setup. This includes their optical characterization, as well as electrical measurements in the time domain (oscilloscope) and in the frequency domain (network- and spectrum analyzer). For the measurement and data processing, we already have a range of computer programs available in our group, so that you can start measuring right away. Depending on your preferences, the project could be completely experimental, or also contain a modelling component. The project is envisioned with students in Applied and Engineering Physics (AEP) and Condensed Matter Physics (KM) in mind, but if you follow another track we are still interested to hear from you. Being curious and wanting to get a feeling for what doing real research is about, is the most important factor. There are no formal requirements on courses taken.

	Advanced sample preparation for SEM/EDS/EBSD with an ion milling system	Petry
	Arbeitsgruppe FRM II Beschreibung Starting fall 2021, the working group “High Density Nuclear Fuels” at the research neutron source Heinz Maier-Leibnitz (FRM II) is looking for a B.Sc. student / working student / internship Advanced sample preparation for SEM/EDS/EBSD with an ion milling system The research working group “High Density Nuclear Fuels” at the research reactor FRM II is working on the qualification of newly-developed high-density nuclear fuels in Europe. The most promising candidates are a metallic uranium-molybdenum alloy fuel (U-Mo) or high-density uranium silicide (U3Si2), both using aluminum-based cladding. Therefore, scientists in the fields of physics, chemistry, engineering, physical technology and computer science are working intensively together on fuel fabrication technologies, the determination of material properties as well as the irradiation behavior of such fuels. Sample preparation is typically required before electron microscope analyzes can be performed. Grinding and mechanical polishing are common preparation techniques to remove damage and flatten the surface. Such conventional techniques introduce surface artifacts like scratches, smearing and delamination especially at interfaces between different materials. These issues can be circumvented by an additional ion milling treatment. During this process, an argon ion beam sputters the sample surface, resulting in an atomic-level clean surface with minimized artifacts and thus enabling analysis of sub-surface structures. Several parameters such as ion energy, angle of beam incidence are adjustable for different applications. The applicant for this topic is supposed to develop optimal recipes of ion milling procedure for fuel samples with our newly purchased advanced ion milling system, possibly followed by electron microscopy and elemental analyses (SEM/EDS/EBSD). Best suited are students studying physics, engineering, materials science or comparable studies. We are looking forward to your application.

The high security standard of FRM II generally requires a security clearance according to the German atomic law. Forschungsfeld Atomphysik (experimentell) (~70%) Atomphysik (Theorie) (~30%)
	Analyse der Flavour-Amplituden in B - K π-Zerfällen	Caldwell
	Arbeitsgruppe Max-Planck-Institut für Physik / Werner-Heisenberg-Institut (MPP) Beschreibung B-Mesons can decay into 4 isospin variants of Kπ pairs. Different combinations of decay processes (tree, colour suppressed tree, penguin, etc) contribute to the decay amplitudes of these decays. Based on the measured branching fractions and CP-violation ratios it is possible to disentangle the magnitude of the various contributions and their relative phases. This allows to constrain theoretical models and even to give hints of deviations from the standard model. In this work the theoretical models should be fitted to the data, checking for inconsistencies and making prediction on what quantities need to be measured in future.

	Analysis of the impedance response of the anode and cathode materials for Li-ion batteries	Bandarenka
	Arbeitsgruppe Physik der Energiewandlung und -speicherung Beschreibung Impedance spectroscopy (IS) is one of the most sensitive characterization techniques to obtain knowledge on batteries. This project aims to monitor the changes in the Li-ion cell caused by temperature, c-rate, cycle number, and different active material loading using IS. The main direction will be preparing of so-called half-cells by using anode or cathode active materials. Thereafter, you will monitor and analyze the impedance responses of the cells under different conditions and be able to explain the physics behind the impedance spectra. This project will involve a literature review, coin cell sample preparation, glovebox usage, impedance spectroscopy, and battery testing. Forschungsfeld Materialphysik (experimentell)
	Anpassung von mehreren Scheitelpunkten mit RAVE	Caldwell
	Arbeitsgruppe Max-Planck-Institut für Physik / Werner-Heisenberg-Institut (MPP) Beschreibung B-Mesons mainly decay in a B->D chain. Since the D decay vertex is displaced from the B decay vertex the determination of the B vertex gets biased if tracks from the D decay are included in the fit. The RAVE package allows in principle to fit multiple vertices and hence separate tracks from B and D decays. It should be studied if this feature can be used to improve the vertex resolution.

	Characterizing CsI coated THGEMs for photon detection	Fabbietti
	Arbeitsgruppe Dichte und seltsame hadronische Materie Beschreibung Traditional devices for photon detection like the Photomultiplier Tube or more recent technologies such as Silicon Photomultipliers are very cost-intensive. Therefore, especially with large area experiments in mind it is very interesting to investigate new ways of detecting photons. In this project we are taking the approach of combining a photosensitive material with a Thick GEM (THGEM) in a gaseous detector. THGEMs are robust, low-cost devices, which can be used for electron multiplication. The THGEM is coated with a photosensitive material and placed within an electrical field. When a photon releases an electron from the material the photo electron drifts in the THGEM hole and undergoes avalanche amplification due to a high electric field that is preset inside the holes. Below the THGEM an anode is used for electron readout. Depending on the gain of the THGEM this could enable single photon detection. In the scope of the thesis CsI coated THGEMs, which are useful in the UV light range, will be characterized and their quantum efficiency will be studied.

Swift ion irradiation is found to be a time- and cost-efficient technique to simulate in-pile irradiation behavior of U-Mo/Al fuels. A new irradiation station will be set up at an international accelerator facility. The irradiation should be performed in a stable and controllable environment.

	Developing a production procedure for epitaxial U-Mo layers with PVD	Petry
	Arbeitsgruppe FRM II Beschreibung Starting from October 2021, the working group “High Density Nuclear Fuels” at the research reactor FRM II is looking for a B.Sc. student / M.Sc. student / working student / internship Developing a production procedure for epitaxial U-Mo layers with PVD The research working group “High Density Nuclear Fuels” at the research reactor FRM II is working on the qualification of newly-developed high-density nuclear fuels in Europe. The most promising candidates are a metallic uranium-molybdenum alloy fuel (U-Mo) or high-density uranium silicide (U3Si2), both using aluminum-based cladding. Therefore, scientists in the fields of physics, chemistry, engineering, physical technology and computer science are working intensively together on fuel fabrication technologies, the determination of material properties as well as the irradiation behavior of such fuels. For metallic uranium-molybdenum fuel systems a diffusion barrier is established using Physical Vapor Deposition (PVD) in order to prevent intermixing. The properties of these layers are essentially determined by their growth structure and can be altered with deposition parameters such as deposition power, applied bias voltage to the substrate and heating. Therefore, the scope of this project is to investigate how single crystalline U-Mo layers can be deposited with Physical Vapor Deposition (PVD). The analytical procedure will involve X-ray Diffraction (XRD), Electron Backscatter Diffraction (EBSD) and Scanning Electron Microscopy (SEM) of the samples for single crystal verification. The practical work will also include sample preparation and polishing techniques. Best suited are students studying physics, engineering, materials science or comparable studies. The scope of the project can be adjusted according to the degree of graduation. We are looking forward to receive your application.

The most promising candidates are a metallic uranium-molybdenum alloy fuel (U-Mo) or high-density uranium silicide (U3Si2), both using aluminum-based cladding. Therefore, scientists in the fields of physics, chemistry, engineering, physical technology and computer science are working intensively together on fuel fabrication technologies, the determination of material properties as well as the irradiation behavior of such fuels. For metallic uranium-molybdenum fuel systems a zirconium diffusion barrier is established using Physical Vapor Deposition (PVD) in order to prevent intermixing with the aluminum cladding. The properties of these multilayers are examined with Scanning Electron Microscopy (SEM), Scanning Transmission Electron Microscopy (STEM) and Transmission Electron Microscopy (TEM). Therefore, the scope of this project is to develop a standardized production procedure with the Focused Ion Beam and Scanning Electron Microscope (FIB-SEM) to shape the multi-layers into a defect-free lamella. The practical work will also include sample preparation and manufacturing, polishing techniques such as Ion Milling and mechanical polishing.

	Development of new approach to study particle correlations using femtoscopy	Fabbietti
	Arbeitsgruppe Dichte und seltsame hadronische Materie Beschreibung One of the most precise and most powerful approaches to probe the strong interaction between different particle pairs is the femtoscopy method [1] which is based on measuring the correlation in the momentum space between hadrons produced at particle colliders such as the LHC. The correlation function is obtained by using the same and mixed event particle pair distributions as functions of their relative momenta. The former carries the information about the interaction while the latter provides information on the available phase-space of the produced pair. Two particles produced in one collision makes the same event pair while the mixed event pairs are constructed by taking two particles from two di erent collisions. The technique of event mixing is a very well working approximation, however, more sophisticated solutions are of increasing interest as the femtoscopic method is used in more and more complicated studies and is being extended to probe the multi-hadron interactions. In this work, a new approach to account for the particle phase space will be elaborated by using marginalized probability distribution functions. Toy Monte Carlo simulations will be used to test the mathematical basis of the method which will be then applied on the proton-proton collision data collected by the ALICE detector to study its feasibility in real experimental conditions.

	Durchstimmung der Amplitude des Spin-Hall-Magnetwiderstands (Thema ist bereits vergeben)	Gross
	Arbeitsgruppe Technische Physik Beschreibung The exchange of spin angular momentum between the localized magnetic moments of a magnetically ordered insulator and the spin polarization of the conduction electrons in an adjacent metallic electrode with large spin-orbit coupling gives rise to interfacial spin mixing. This manifests itself as a characteristic angular dependence of the metal’s resistivity on the magnetization direction of the insulator’s magnetic sublattices, denoted as “spin Hall magnetoresistance (SMR)”. The effect was first observed in ferrimagnetic Y₃Fe₅O₁₂/Pt thin film heterostructures and recently also reported in antiferromagnetic NiO/Pt and α-Fe₂O₃/Pt. While the phase of the SMR oscillations is well understood and explained by theory, their amplitude, however, is still a matter of debate, since various extrinsic as well as intrinsic parameters play a crucial role. The goal of this master’s thesis is to study the correlation of the SMR amplitude to the density of magnetic ions and their spin magnetic moments in different magnetically ordered insulating oxides. We are looking for a master student interested in thin film technology for the fabrication and investigation of magnetic insulator/normal metal bilayer structures. The master project will provide a comprehensive introduction into laser molecular beam epitaxy (laser-MBE) as well as electron beam physical vapor deposition, high-resolution X-ray diffraction (HRXRD), atomic force microscopy (AFM), superconducting quantum interference device (SQUID) magnetometry, photolithography, and angle-dependent magnetotransport measurements.

	Entwicklung eines fluoreszierenden DNA-Topologie Sensors für Single Molekül Mikroskopie	Duderstadt
	Arbeitsgruppe Struktur und Dynamik molekularer Maschinen Beschreibung While the double-helical structure of duplex DNA is advantageous for the storage and maintenance of genetic information, it poses major challenges during essential cellular processes, such as transcription and replication, when the information-rich DNA bases must be accessed. Separation of the two single strands leads to the build-up of superhelical tension, which, if left unresolved, exerts extreme forces in the form of torque that disrupts critical enzymatic events on chromosomes. In this project, recently discovered topology sensing proteins will be fluorescently labeled and used in single-molecule imaging experiments to directly visualize DNA topology dynamics. These tools will then be used to characterize how topological energy migrates around the replication fork and where overwinding accumulates leading to replication fork collapse. In this project protein biochemistry techniques will be used to characterise the DNA binding properties of the labeled topology sensors. DNA substrates will be generated with defined topologies suitable for imaging. Single immobilized DNA molecules together with labeled fluorescent sensors will be imaged using multiwavelength TIRF microscopy. Dynamics will be quantified using custom written Fiji plugins and python notebooks. During each stage of the project supervision and needed expertise will be provided.

	Epitaxial growth of single crystalline U or U-Mo layers with PVD	Petry
	Arbeitsgruppe FRM II Beschreibung Starting from October 2021, the working group “High Density Nuclear Fuels” at the research neutron source Heinz Maier-Leibnitz (FRM II) is looking for a B.Sc. student / M.Sc. student / working student / internship Epitaxial growth of single crystalline U or U-Mo layers with PVD Metallic Uranium shows a rich phase diagram. Elemental Uranium solidifies at 1135°C in the bcc -phase to transform upon cooling first to -Uranium (776°C) and finally (555°C) to the hexagonal -Uranium, which is the stable phase at room temperature. We intend to measure the phonon dispersion of -U, which ultimately needs single crystals, eventually as thin epitaxial films. We foresee two alternatives to reach this goal. Either it is possible to grow -U by physical vapor deposition (PVD) on a specially selected single crystalline substrate, which forces the Uranium to condense on the substrate in bcc structure or alternatively about 8 wt% Mo are alloyed to U, which stabilizes the high temperature -U to room temperature and epitaxial growth by PVD. The latter one is straight forward with the draw back to compromise by alloying a further metal, i.e. Mo. Therefore, the scope of this project is to investigate how single crystalline U or U-Mo layers can be deposited by means of Physical Vapor Deposition (PVD). The analytical procedure will involve X-ray Diffraction (XRD), Electron Backscatter Diffraction (EBSD) and Scanning Electron Microscopy (SEM) of the samples for single crystal verification.

	Exploring the properties of Quark-Gluon Plasma with anisotropic flow measurements at the Large Hadron Collider The	Fabbietti
	Arbeitsgruppe Dichte und seltsame hadronische Materie Beschreibung The matter produced in ultra-relativistic heavy-ion collisions resembles the Quark-Gluon Plasma (QGP), which is an extreme state of nuclear matter consisting of deconfined quarks and gluons. Such a state existed in the early Universe, just a few microseconds after the Big Bang. Its properties can be experimentally accessed by measuring the azimuthal anisotropies in the momentum distribution of produced particles in heavy-ion collisions, for instance, in lead-lead collisions reconstructed with the ALICE experiment at CERN's Large Hadron Collider (LHC). Of particular interest in this context is the anisotropic flow phenomenon, which is an observable directly sensitive to the properties of QGP. In this project, we introduce the basics of anisotropic flow and corresponding analyses techniques, and we guide a student throughout all steps needed for its final measurement, in the large-scale LHC datasets distributed on Grid. We start a project by briefly introducing a theoretical framework within which an anisotropic flow phenomenon can be defined and quantified. Next, we introduce sophisticated multi-particle correlation techniques, which were developed recently by experimentalists particularly for anisotropic flow measurements. We go in detail through the practical implementation of multi- particle correlations, students are expected at this point to perform some simple analytic calculations, and to learn and perform programming tasks both in ROOT and AliROOT. ROOT is the object-oriented analysis frame- work written in C++ programming language, and it is used at the moment as a default software in high-energy physics by all major collaborations world- wide, while AliROOT is the more speci c analysis framework developed by ALICE experiment, and which is based on ROOT. We wind up the project by letting the student do an independent ani- sotropic flow analysis with his/her own newly developed code in AliROOT, utilizing multi-particle correlation techniques, over real heavy-ion collisions collected by ALICE at LHC, and stored on Grid.

	KI and Machine Learning tools to analyze organogenesis.	Bausch
	Arbeitsgruppe Zellbiophysik Beschreibung Recent progress enabled to build organs in the cell culture. the so called organoids are promising model systems to understand not only the physical basis of organogenesis but also have the potential to revolutionize drug development efforts. The complexity of the structure forming process requires the deployment of machine learning tools. These are already ideally suited to recognize and classify the evolving structures, in the next step we aim to push the KI based methods further - to be able to predict the developmental phases. Within this thesis the KI methods will be developed and applied to high throughput microscopy data sets. Forschungsfeld Biologische Physik (experimentell)
	Modelling single photon sources for optical quantum circuits (Thema ist bereits vergeben)	Poot
	Arbeitsgruppe Quantentechnologien Beschreibung For quantum technology it is very important to have sources for single photons. One of the techniques that can be used to create these, is called spontaneous parametric down conversion, or SPDC for short. Here photons with a high frequency can split into two daughter photons with about half the frequency. An important point in this technique is so-called phase matching: the low and high frequency photons should travel at the same speed through the nonlinear material. This is often achieved by using special crystals that have to be oriented carefully. For applications we want to integrated these sources on photonic chips. In this project we will expore the phase matching in waveguides using photonic simulations of waveguides. Forschungsfeld Nanostrukturen (Theorie) (~50%) Optik (Theorie) (~50%)

	Performance evaluation of humidified gaseous particle detectors	Fabbietti
	Arbeitsgruppe Dichte und seltsame hadronische Materie Beschreibung Micropattern gas detectors (MPGD) are a type of particle detector used in many large high energy physics experiments (Atlas, CMS, ALICE). MPGDs work by amplifying the signals generated by charged particles traversing a gas volume. This is made possible by using amplification structures with micrometre scale patterns. There are different designs of such detectors, which include Gas Electron Multiplier (GEM) and Micro-Mesh Gaseous Structure (Micromegas). These are both highly scalable and offer good performance. Still, one of the main limiting factors for the long-term stable operation of MPGDs is the formation of electrical discharges inside the amplification structures. Due to this, there has been an extensive effort over the years to understand and develop methods to mitigate these discharges. One of the remaining questions however is how the humidity (the water content) of the used gas mixture affects the formation of discharges in MPDS. This project aims to conduct the first comprehensive studies investigating the correlation between gas humidity and MPGD discharge stability. For this task, a dedicated detector chamber will be used with modifications to the gas system which enables the precise control of the ambient humidity levels. This venture is a great entry point for anyone interested in particle detector hardware research and development. The achieved results of which might end up shaping the next generation of cutting-edge high energy physics experiments!

	Plasma parameters of a PVD coating process for U-Mo fuels	Petry
	Arbeitsgruppe Funktionelle Materialien Beschreibung Starting from November 2021, the working group “High Density Nuclear Fuels” at the research reactor FRM II is looking for a B.Sc. student / working student / internship Plasma parameters of a PVD coating process for U-Mo fuels The working group “High Density Nuclear Fuels” at the Research Neutron Source Heinz Maier-Leibnitz (FRM II) is working on the qualification of newly-developed high-density nuclear fuels in Europe. The most promising candidates are a metallic uranium-molybdenum alloy fuel (U-Mo) or high-density uranium silicide (U3Si2), both using aluminum-based cladding. Therefore, scientists in the fields of physics, chemistry, engineering, physical technology and computer science are working intensively together on fuel fabrication technologies, the determination of material properties as well as the irradiation behavior of such fuels. For metallic uranium-molybdenum fuel systems a diffusion barrier is established using Physical Vapor Deposition (PVD) in order to prevent intermixing. The scope of this project is to do a parameter study on a PVD device regarding the ion and electron bombardment during the coating of the substrate material in order to get a better understanding of the growing layer. This will be used to better control the growth structure of the zirconium coatings in a way that it acts as a good diffusion barrier and also withstands the mechanical stresses of subsequent cladding applications. The practical work may also include sample preparation and polishing techniques. Best suited are students studying physics, engineering, materials science or comparable studies. We are looking forward to receive your application. Further information on the fuel development at FRM II can be found at https://www.frm2.tum.de/en/fuel-development For questions and applications, please contact Bruno Baumeister (bruno.baumeister@frm2.tum.de; +49 89 289 13967) Christian Schwarz (christian.schwarz@frm2.tum.de; +49 89 289 14759) Framework conditions The tasks typically involve working in radiation protection areas with open handling of radioactive materials such as uranium.

	Source of energy for a gigantic cell	Alim
	Arbeitsgruppe Theorie biologischer Netzwerke Beschreibung Where does the energy for the gigantic cell Physarum polycephalum come from? Physarum is a giant unicellular organism, that can grow up to centimeter-size. The organism behaves intelligently and makes decisions through peristaltic pumping, which drives efficient transport of signals and nutrients throughout Physarums body. To supply every part of its large cell body with energy, it needs a huge number of mitochondria (the powerhouse of the cell). You will develop an assay to clarify the appearance of these organelles using fluorescence microscopy and spectrometry. Moreover, you will get the chance to image the organism and find out where the mitochondria are hidden and how many are there. With that, you might be able to set the foundation for important assumptions about the energy the organism consumes. Prerequisities: Curiosity on how cell biology goes hand in hand with physics and a fascination for uncovering the beauty of nature under the microscope.

	Stabile Muster die der Strömung widerstehen (Thema ist bereits vergeben)	Alim
	Arbeitsgruppe Theorie biologischer Netzwerke Beschreibung Der intelligente Schleimpilz Physarum polycephalum ist dafür bekannt, dass er komplexe Probleme löst, wie z.B. den kürzesten Weg durch ein Labyrinth zu finden. Dabei ist noch nicht einmal klar, wie der Organismus ‘vorne’ und ‘hinten’ in seinem netzwerkförmigen Körper unterscheidet. Kann in dem flüssigen Inneren des Netzwerks trotz starker Strömung ein chemischer Gradient bestehen, der vorne und hinten markiert? In Deinem Projekt untersuchst Du, ob Zellkerne, die chemische Botenstoffe ausschütten, durch ihren Wechsel zwischen festhalten und mitschwimmen in dem Netzwerk einen stabilen chemischen Gradienten erzeugen können. Dazu löst Du die Bewegungsgleichungen der Zellkerne und der Botenstoffe numerisch und quantifizierst unter welchen Bedingungen sich ein Gradient an Botenstoffen einstellen kann. Deine theoretischen Vorhersagen stehen dabei im engen Austausch mit experimentellen Beobachtungen in unserer Arbeitsgruppe. The intelligent slime mould Physarum polycephalum is known for solving complex problems, such as finding the shortest path through a maze. Yet it’s not even clear how the organism distinguishes ‘front’ and ‘back’ in its network-like body. Can a chemical gradient exist in the fluid interior of the network that marks front and back, despite strong flow pervading the network? In your project, you will investigate whether cell nuclei that secrete chemical messengers can create a stable chemical gradient in the network by alternating between staying fixed and floating along with the flow. To do this, you will solve the equations of motion of the cell nuclei and the chemical messengers numerically and quantify under which conditions a gradient of chemical messengers can occur. Your theoretical predictions are in close exchange with experimental observations in our group.

	Strategie für den Umgang mit Mehrfachbewerbern	Caldwell
	Arbeitsgruppe Max-Planck-Institut für Physik / Werner-Heisenberg-Institut (MPP) Beschreibung In a typical analysis at the Belle II experiment (and of course in many other experiments) B decays are reconstructed by combining different reconstructed tracks and selection combinations which best fit the decay type search for. Often more than one combination which fits the selction criteria is found in a single event. There are different strategies to deal with such multiple candidates: using all equally, selecting ‘best candidate’ using additional criteria, ignoring such events, and multi-dimensional fits. Using Monte Carlo studies the advantages and disadvantages of these strategies should be investigated: Do they introduce a bias, do they make optimal use of the available statistics and what kind of systematic uncertainties might arise.

	Studying the spacial and kinematic properties of the particle emission in pp collisions at the LHC	Fabbietti
	Arbeitsgruppe Dichte und seltsame hadronische Materie Beschreibung In recent years, the method of femtoscopy has been successfully applied to make use of two-particle momentum correlations to investigate the strong force acting upon a pair of hadrons [Nature 588 (2020) 232-238]. This has been achieved by creating, at TUM, a numerical framework capable of modeling the pair-wise particle emission profile [Phys.Lett.B 811 (2020) 135849]. Nevertheless, the required input is model dependent, as it requires knowledge on the spacial and momentum correlations of the particles at the moment of their production. The task of the participant is a continuation of the existing work, with the specific duty of studying the possibility of applying more generic methods to obtain information on the initial properties of the emission region. Finally, the bachelor candidate will implement the procedure within a universal framework, that is to be used in future N-body femtoscopic studies. The requirements are: 1) Basic knowledge and interest in KTA. 2) Basic knowledge and interest in programming. The gained experience is: 1) The basics of the statistical thermal model analysis of particle production at LHC. 2) Understanding of the femtoscopy method, with a stress on the particle emission in high-energy proton-proton collisions. 3) Working with numerical Monte-Carlo models. 4) Improvement of the programming skills, in particular C++ and the ROOT framework, both of which are essential in the field of data analysis. In addition, basic knowledge related to Python and Linux will be gained. Forschungsfeld Teilchen und Felder (experimentell) Betreuer(innen) Dimitar Mihaylov
	Study the absorption of antihelium-4 in ALICE experiment at CERN LHC	Fabbietti
	Arbeitsgruppe Dichte und seltsame hadronische Materie Beschreibung Dark Matter (DM) is believed to account for roughly 27% of the mass-energy of our Universe, and its nature remains one of the most intriguing unsolved questions of modern physics. This massive hole in our knowledge drives multiple experimental searches for DM, and one of the indirect ways to search for DM is to look for the annihilation or decay of DM particles into ordinary (anti)particles such as light (anti)nuclei as employed by several balloon- and space-borne experiments. Low-energy light antinuclei (e.g. antihelium-4) are particularly promising signals for these indirect DM searches, since the background stemming from ordinary collisions between cosmic rays and the interstellar medium is expected to be low with respect to the DM signal. In order to reliably estimate the detection probability of interesting events such as DM -> helium-4 + antihelium-4 + ..., the interaction probability of antihelium-4 with ordinary matter (like interstellar medium, Earth's atmosphere) must be measured, since it defines the amount of antihelium-4 particles lost on the way to detector. However, nuclear inelastic cross sections of antihelium-4 + A processes are completely unknown, forcing current estimates of expected antihelium fluxes near Earth to rely on extrapolations and modelling. The topic of the here advertised master project deals with the measurement of these interactions using the ALICE detector. In heavy-ion collisions at LHC energies (anti)helium-4 nuclei are produced in significant amounts, and unique tracking and PID capabilities of the ALICE experiment make it possible to reliably detect the (anti)helium-4 nuclei in different sub-detector systems. This allows us to quantify the inelastic interaction probability of (anti)helium-4 with the ALICE detector material. This project will be structured in the following way: Analysis of the inclusive spectra of helium-4 and antihelium-4 nuclei in PbPb collisions at TeV Evaluation of the effective antihelium-4 + A inelastic cross sections Estimation of the antihelium-4 rates expected for different DM models in current and future satellite experiments Forschungsfeld Teilchen und Felder (experimentell) Betreuer(innen) Ivan Vorobyev

In the presence of a random potential, a system of electrons can become insulating; a phenomenon known as many-body localization (MBL) that has been envisioned by the Nobel laureate Phil Anderson. However, even beyond the vanishing transport such systems have very intriguing properties. For example, many-body localization describes an exotic state of matter, in which fundamental concepts of statistical mechanics break down.

Studienabschluss und Zeugnisdokumente

Die letzte Prüfungsleistung ist in der Regel das Bachelorkolloquium. Im Normalfall übermitteln die Gutachter(innen) die Ergebnisse unmittelbar nach dem Kolloquium an das Dekanat, so dass die Leistungen aus Bachelorkolloquium und Bachelorarbeit spätestens am nächsten Tag in TUMonline vorliegen. Sobald alle Leistungen der Bachelorprüfung in TUMonline letztgültig verbucht sind, wird Ihr Abschluss an das Prüfungsamt Garching zwecks Erstellung der Abschlussdokumente gemeldet. Dort kann dann auch eine Studienabschlussurkunde (sogenanntes "vorläufiges Zeugnis") erstellt werden. Das Prüfungsamt erstellt die Abschlussdokumente und benachrichtigt Sie schriftlich, wenn diese abgeholt werden können.
