Orbituary for Professor Lothar Köster
2015-09-10 – Shortly before his 93rd birthday Prof. Dr. Lothar Köster passed away on September 7, 2015 in Garching. The physicist was Technical Director of the first German research reactor Garching (FRM) for 29 years – from 1958 until 1987. The physics department is very grateful for his achievements and and shares the grief of his family.
IceCube bestätigt die astrophysikalische Natur der Hochenergie-Neutrinos
2015-09-09 – Das Südpol-Observatorium IceCube berichtet von der Beobachtung weiterer Neutrinos aus den Tiefen des Weltalls. Die nun in der Fachzeitschrift Physical Review Letters veröffentlichte Untersuchung bestätigt damit, dass die hoch energiereichen Neutrinos, deren Beobachtung durch IceCube vor zwei Jahren in Science publiziert wurde, ihren Ursprung tatsächlich außerhalb unseres Sonnensystems haben. Die Forschungsgruppe von Prof. Dr. Elisa Resconi vom Exzellenzcluster Universe der Technischen Universität München ist Mitglied der IceCube-Kollaboration.
Dark matter: Searching for "lightweights" with CRESST
2015-09-08 – The Earth, planets, stars, and galaxies form only the visible portion of the matter in the universe. Greater by far is the share accounted for by invisible “dark matter”. Scientists have searched for the particles of dark matter in numerous experiments – so far, in vain. With the CRESST experiment, the search radius can be considerably expanded: The CRESST detectors are being overhauled and are then able to detect particles whose mass lies below the current measurement range. As a consequence, the chance of tracking dark matter down goes up.
Precise comparison of light nuclei and antinuclei
2015-09-07 – Our existence is still a great mystery in theoretical physics. Why did anti-matter disappear almost completely from our universe, whereas matter did not? Scientists are attempting to solve this mystery at the particle accelerator of the major European research institute at CERN. The ALICE collaboration has now published the most precise measurement of the properties of light atomic nuclei and anti-nuclei ever made in the journal “Nature Physics”. Scientists from the physics department at Technical University of Munich (TUM) are working on new detectors for the ALICE experiment which will improve the precision of future measurements.
New exotic particle state puzzles theorists
2015-09-04 – Scientists from the COMPASS collaboration at CERN have observed a new exotic combination of light quarks. The discovery was made in an experiment that shoots pions at close to the speed of light towards a liquid hydrogen target. Now, the ball is in the theoretical scientists’ court to find an explanation for the new particle status. Some explanations have been proposed, but it has been impossible so far to correctly describe all characteristics of this exotic new feature. Scientists from the Physik-Department of Technische Universität München and the Excellence Cluster Universe had a leading role in the data analysis of the new finding.
Neutrons observe the dynamics of magnetic helices
2015-09-03 – Scientists at the Physik-Department of TUM and the MLZ have confirmed a model describing excitations in magnetic helices. A modification of the MIRA instrument at FRM II allows to record these spin-wave excitations (helimagnons).
Dr. Rikkert Frederix receives highly-endowed award of the Humboldt Foundation
2015-08-27 – Particle physicist Dr. Rikkert Frederix is to receive the highly-endowed Sofja Kovalevskaja Award of the Alexander von Humboldt Foundation. He will establish his own research group in the Physics Department of Technical University of Munich (TUM) with the goal of discovering what holds the world together at its innermost core.
Ultra short laser pulses generate mini X-ray source for 3D imaging of soft tissue
2015-08-26 – Researchers of the Max Planck Institute for Quantum Optics, the Technical University of Munich (TUM) and Ludwig-Maximilians-Universität München (LMU) have developed a miniature X-ray source with laser light. They used this light-generated radiation in combination with phase-contrast X-ray tomography and captured three-dimensional images of ultrafine details of a fly measuring just a few millimeters. Until now, such radiation could only be produced in expensive ring accelerators measuring several kilometers in diameter. The newly developed instruments only require a university laboratory.
Probing pattern formation and dynamics of nanoscale "swarms"
2015-08-25 – “Flocking” or “swarming” behavior is omnipresent in the living world, observed in birds, fish, and even bacteria. Strikingly similar collective action can also be seen in biomolecules within and between cells. Such self-organization processes are the basis of life – without them no living cell would exist – yet they are not well understood. New insights into how this action is coordinated at the biomolecular level are emerging from studies of a model system based on actin filaments. Experimental evidence proves the inadequacy of widely accepted explanations, according to collaborators at the Technical University of Munich (TUM), Ludwig-Maximilians-Universität München (LMU), and the Max Planck Institute for the Physics of Complex Systems (MPI-PKS).
50 years of cutting-edge research at the "Physik-Department"
2015-07-22 – The German news magazine “Der Spiegel” called it the “second Moessbauer effect” when the Technical University of Munich (TUM), succumbing to pressure by its physics professors, restructured the physics institutes to a Department of Physics in the vein of the American model. The new structure, which was revolutionary at the time, remains in place to this day and formed the basis for its success in the German Excellence Initiative and the superb world-wide reputation of physics at the Technical University of Munich.
Zentrum für Protein-Forschung gegründet
2015-06-25 – Die Technische Universität München (TUM) kombiniert ihre vielfachen Kompetenzen in der Proteinforschung und gründet das „TUM Center for Functional Protein Assemblies (CPA)“. Es wird fakultätsübergreifend die Funktionsweisen und Wirkprinzipien von Proteinen erforschen – Schlüssel zum Verständnis von Zellen, Geweben und Organen. Auf dieser Grundlage soll das interdisziplinäre Zentrum biomedizinische Anwendungen entwickeln, etwa zur Heilung von Krankheiten, die durch Störungen im Zusammenspiel der Biomoleküle verursacht sind. Die Gemeinsame Wissenschaftskonferenz (GWK) hat heute beschlossen, dass Bund und Land einen Neubau des CPA auf dem Campus Garching mit insgesamt rund 40 Millionen Euro fördern.
Optimized printing process enables custom organic electronics
2015-06-17 – They are thin, light-weight, flexible and can be produced cost- and energy-efficiently: printed microelectronic components made of synthetics. Flexible displays and touch screens, glowing films, RFID tags and solar cells represent a future market. In the context of an international cooperation project, physicists at the physics department of TUM have now observed the creation of razor thin polymer electrodes during the printing process and successfully improved the electrical properties of the printed films.
New textbook: Physics of energy conversion
2015-06-03 – Prof. Katharina Krischer and Konrad Schönleber from Physik-Department have published a new textbook on the “Physics of energy conversion”.
The weakest magnetic field in the solar system
2015-05-12 – Magnetic fields easily penetrate matter. Creating a space practically devoid of magnetic fields thus presents a great challenge. An international team of physicists has now developed a shielding that dampens low frequency external magnetic fields more than a million-fold. Using this mechanism, they have created a space that boasts the weakest magnetic field of our solar system. The physicists now intend to carry out precision experiments there.
