Light in the nanoworld
2019-08-01 – An international team headed up by Alexander Holleitner and Jonathan Finley, physicists at the Technical University of Munich (TUM) has succeeded in placing light sources in atomically thin material layers with an accuracy of just a few nanometers. The new method allows for a multitude of applications in quantum technologies, from quantum sensors and transistors in smartphones through to new encryption technologies for data transmission.
The physiology of survival
2019-07-22 – Bacteria do not simply perish in hunger phases fortuitously; rather, the surrounding cells have a say as well. A research team from the Technical University of Munich (TUM) has now discovered that two factors, above all, decide over life and death: the energy required to continue living and the efficiency with which surviving cells can recycle biomass from dead cells.
What is the perfect quantum theory?
2019-07-12 – For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.
2019-07-09 – With a new spray coating process, very uniform layers of cellulose nanofibers (CNF) can be produced on an industrial scale. X-ray investigations at DESY as well as investigations with an atomic force microscope and neutron scattering at the MLZ, show how the layer is structured and can be tailored for different purposes. A Swedish-German research team led by DESY scientist Adj. Prof. Dr. Stephan Roth presents its structural analyses in the journal Macromolecules .
Activity of fuel cell catalysts doubled
2019-07-03 – An interdisciplinary research team at the Technical University of Munich (TUM) has built platinum nanoparticles for catalysis in fuel cells: The new size-optimized catalysts are twice as good as the best process commercially available today.
Talk: "Quantum technology: 100 million € for Garching
2019-07-02 – Quantencomputer, die mehr leisten als unsere heutigen Supercomputer, abhörsichere Quantenkommunikation, hochempfindliche Quantensensoren: Grundlage für diese faszinierenden Anwendungsfelder sind die „Quantentechnologien 2.0“ – und Garching soll durch Investitionen von mehr als 100 Mio. Euro ein international führendes Zentrum für diese wichtigen Zukunftstechnologien werden.
Immortal quantum particles
2019-06-27 – Decay is relentless in the macroscopic world: broken objects do not fit themselves back together again. However, other laws are valid in the quantum world: new research shows that so-called quasiparticles can decay and reorganize themselves again and are thus become virtually immortal. These are good prospects for the development of durable data memories.
Cooling for quantum electronics
2019-06-12 – The start-up kiutra is the first company in the world to have succeeded in developing a permanent magnetic cooling system to reach temperatures close to absolute zero. Such temperatures are, for example, required for the operation of quantum computers. The system was set up by a team of researchers from the Physics Department at the Technical University of Munich (TUM).
Exceptions become the rule
2019-05-02 – Electrons and their atomic nuclei influence their respective motions in more materials than previously assumed. Scientists from the Technical University of Munich (TUM) and the Forschungszentrum Jülich made this discovery during measurements conducted at TUM’s research neutron source Heinz Maier-Leibnitz (FRM II). Possible applications for the effect they identified include data processing and zero-loss transmission of electricity.
Christoph Hugenschmidt appointed as adjunct professor
2019-04-08 – PD Dr. Christoph Hugenschmidt has been apointed adjunct professor for the subject “Physics with positrons” at the Physics Department of the Technical University of Munich (TUM). Thereby TUM recognizes the scientific achievements of the 49-year-old as well as his years of engagement to teaching. In an interview, Prof. Dr. Christoph Hugenschmidt explains the research field of positrons, which he established at TUM.
TUM physics among the top 16 worldwide
2019-02-27 – The Technical University of Munich (TUM) is ranked among the 25 best universities worldwide in the areas of engineering and the natural sciences. TUM also placed in the top 50 for 10 individual subjects according to the “QS World University Rankings by Subject 2019”. TUM physics is at the global rank 16, the best of the German universities.
Geisterteilchen als faszinierende Lichter und Klänge
2019-02-05 – Ein faszinierendes Kunsterlebnis bieten das Physik-Department der Technischen Universität München (TUM) und der SFB1258 am Wochenende des 9. und 10. Februar 2019 in der „Reaktorhalle“ der Musikhochschule in der Luisenstraße. Die Licht- und Klang-Installation AIS3 [aiskju:b] des Komponisten und Konzeptkünstlers Tim Otto Roth ist an beiden Tagen von 10 bis 20 Uhr geöffnet. Der Eintritt ist frei.
Elisa Resconi appointed as full professor
2019-02-05 – The internationally renown neutrino physicist Elisa Resconi, spokesperson of the Collaborative Research Centre 1258, has been appointed as full professor for “Experimental Physics with Cosmic Particles” at the Physics Department of Technical University of Munich.
90th birthday of Rudolf Mößbauer
2019-01-31 – Heute wäre der Nobelpreisträger Rudolf Mößbauer, der den größten Teil seiner akademischen Laufbahn an seiner Alma Mater in München und Garching verbrachte, 90 Jahre alt geworden. Der frühere Ordinarius für Experimentalphysik der TUM (1965-1997) erhielt die höchste wissenschaftliche Auszeichnung 1961 für den experimentellen Nachweis der rückstoßfreien Kernresonanzabsoprtion. Aus Anlass des Geburtstages berichtet der Deutschlandfunk.
Protein engineering extends immune cell vocabulary
2019-01-25 – Small infections can be fatal: Millions of people die each year from sepsis, an overreaction of the immune system. A new immune signaling molecule, designed by a research team from the Technical University of Munich (TUM), now provides the basis for potential new approaches in sepsis therapy.
Research at high pressure reveals details on phase transition
2019-01-24 – Unlike ice and other inorganic substances, most polymers do not show sharp phase transitions. Instead of melting at a well defined temperature, they gradually soften without significantly changing their microscopic structure. Yet some so-called thermoresponsive polymers show a drastic and discontinuous phase transition with rapid structural changes. An international team of scientists led by Prof. Christine M. Papadakis from TUM’s Physics Department has carried out a series of different experiments at high pressure, that sheds new light on the physical mechanism behind this peculiar behavior.
