A new fur for the Quantum Cat

2022-09-02 – Be it magnets or superconductors: materials are known for their various properties. However, these properties may change spontaneously under extreme conditions. Researchers at the Technische Universität München (TUM) and the Technische Universität Dresden (TUD) have discovered an entirely new type of such phase transitions. They display the phenomenon of quantum entanglement involving many atoms, which previously has only been observed in the realm of few atoms.

Waves on circular paths

2022-03-09 – Just as electrons flow through an electrical conductor, magnetic excitations can travel through certain materials. Such excitations, known in physics as “magnons” in analogy to the electron, could transport information much more easily than electrical conductors. An international research team has now made an important discovery on the road to such components, which could be highly energy-efficient and considerably smaller.

New materials for quantum technologies

2021-12-23 – While conventional electronics relies on the transport of electrons, components that convey spin information alone may be many times more energy efficient. Physicists at the Technical University of Munich (TUM) and the Max Planck Institute for Solid State Research in Stuttgart have now made an important advance in the development of novel materials for such components. These materials may also be the key to quantum computers that are less susceptible to interference.

Surface metallicity in iron silicide

2021-11-25 – Researchers at the Physics Department at TUM and the Chemistry Department at ENS Paris microscopically verify a low-temperature conduction channel featuring high electron mobility on the surface of single crystal FeSi, proving it to be the result of interfacial symmetry breaking.

Vortex around frozen magnets

2020-03-19 – Water freezes at sub-zero temperatures, by forming small islands of ice germs first. Magnetic structures, so-called skyrmions, behave very similarly, as scientists have discovered with the help of neutrons for the first time at the Physics Department and the Heinz Maier-Leibnitz Zentrum (MLZ).

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.

Magnetic vortices: twice as interesting

2018-07-11 – For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Center for Quantum Engineering comes to Garching

2018-04-30 – In recent years, a globally esteemed research focus on quantum technologies has developed on the Garching campus. The German Council of Science and Humanities now supports the creation of a new central institute at the Technical University of Munich (TUM) that will link this focus with the engineering sciences and aims to transfer quantum systems into real-world applications more quickly. Should the Joint Science Conference (GWK) follow this recommendation on 29 June, the German Federal Government and the Free State of Bavaria will share the costs of around 40 million euro equally.

EU funding for pioneering projects

2018-04-19 – The properties of quantum matter and an as yet unproven form of decay that atomic nuclei undergo: this are the topics of two projects at TUM’s Physics Department that receive highly endowed Advanced Grants from the European Research Council (ERC). Another project about biological nanodevices is supported by an “Proof of Concept Grant”.

Christian Pfleiderer and Peter Böni receive Europhysics prize

2016-05-30 – Experimental physicists Prof. Christian Pfleiderer and Prof. Peter Böni from the physics department of TUM are awarded the European Physical Society’s prestigious Europhysics Prize. The prize is awarded for the “discovery of a skyrmion phase in manganese silicon” and shared with three theoretical physicists: Prof. Alex Bogdanov (Dresden), Prof. Achim Rosch (Cologne) and Prof. Ashvin Vishwanath (Berkeley).

Max Born prize awarded to Christian Pfleiderer

2015-11-20 – The Institute of Physics (IOP) and the German Physical Society (DPG) have jointly awarded the Max Born Prize to Christian Pfleiderer of TUM’s Physik-Department.
