New Collaborative Research Center in Mathematics approved

On November 18th 2016 the DFG approved a new Collaborative Research Center (CRC) which is an integral part of the research program of QM2. The CRC Symplectic Structures and Techniques in Geometry, Algebra and Dynamics (speaker Hansjörg Geiges, Cologne) joins the forces of, on the one hand, mathematicians who have beensocialized in symplectic geometry and, on the other, scientists working in areas that have proved important for the cross-fertilization of ideas with symplectic geometry, notably dynamics and algebra.
In addition, the CRC intends to explore connections with fields where, so far, the potential of the symplectic viewpoint has not been fully realized or, conversely, which can contribute new methodology to the study of symplectic questions (e.g. optimization, computer science).
A group from Bochum and two further researchers from Münster join this QM2 initiative.

Charlotte Herbig receives the 2016 Wayne B. Nottingham Prize

Charlotte Herbig (II. Physikalisches Institut) received this year's Nottingham Prize at the 76th Physical Electronics Conference (PEC) that took place June 20-23 at University of Arkansas, USA. The Nottingham Prize has been first awarded in 1966 at the Massachusetts Institute of Technology (MIT) in honor of Professor Wayne B. Nottingham. Since then, it awards the best research paper of a junior scientist in the field of surface and interface science based on work done for a PhD. The winner is elected by a jury after a full day of contest, where 20 preselected contestants present their research in scientific talks.

Charlotte Herbig won the prize for her work on ion irradiation of two-dimensional (2D) materials. She discovered that 2D materials like graphene act as a one-way valve for energetic particles leading to highly pressurized blisters that do not release the trapped gas up to extremely high temperatures. 

Charlotte Herbig received her Master's at the University of Cologne, is a member of the Bonn-Cologne Graduate School of Physics and Astronomy and currently a PhD student in the group of Prof. Michely.

“PeroBOOST” project researches development of solar cells from perovskites

QM2 member Klaus Meerholz and his group

have started the “PeroBOOST” project together with AIXTRON SE, Enerthing GmbH, Lunovu GmbH, SOLUXX GmbH, the Center for Organic Electronics Cologne (ZOEK) gGmbH, the Fraunhofer ISE Laboratory and Service Center Gelsenkirchen, and Duisburg-Essen University.

The basis for this three-year project (03/2016-02/2019) is the recent discovery of the superb properties of organo-perovskite materials for efficient solar cells. 
“PeroBOOST” is being supported with funds from the European Regional Development Fund  (ERDF) 2014-2020.

Achim Rosch receives the 2016 Europhysics Prize

Achim Rosch (Institute for Theoretical Physics) receives the 2016 Europhysics Prize of the European Physical Society for his theoretical work on skyrmion physics in MnSi. The award is shared with his experimental colleagues C. Pfleider und P. Böni (TU Munich) as well as theoreticians A.N. Bogdanov (IFW Dresden) and A. Vishwanath (UC Berkeley). Skyrmions are magnetic whirls which can lead to a novel magnetic state of topological nature: a magnetic skyrmion crystal. Such a skyrmion crystal was first observed in MnSi by neutron scattering experiments in Munich in close collaboration with Achim Rosch’s theory group in Cologne. Interest in such novel spin textures has been driven as skyrmions give rise to a topological Hall effect and can be moved by currents much smaller than those required to displace domain walls thus opening the door to applications in data storage.

Since 1975 the Europhysics Prize is awarded every 2 years by the Condensed Matter Division of the European Physical Society for outstanding achievement in condensed matter physics. The official announcement of the European Physical Society can be found at 2016 Europhysics Prize.

Our congratulations to Achim Rosch for this well deserved recognition.

Two collaborative reasearch centers approved

On May 25th 2016 the DFG approved two Collaborative Research Centers (CRC) which are an important part of the research program of QM2.

The CRC Dynamics and Control of Quantum Materials: Topology, Spin-orbit Coupling and Correlations (speaker Paul van Loosdrecht, Cologne) investigates how spin-orbit coupling induces new states of matter, often with special topological properties. Two groups from Bonn and Jülich join this QM2 initiative.

The CRC Entangled States of Matter (speaker Alexander Altland) is a collaboration of scientists from Cologne, Berlin, Copenhagen, and the Weizmann institute in Israel. Combining concepts from quantum information theory, topology and solid state physics the CRC investigates new concept to realize quantum entanglement in novel quantum device.

Maria Hermanns receives Max Delbrück prize for junior researcher

The QM2 member Dr. Maria Hermanns (Institute for Theoretical Physics) receives the Max Delbrück prize for junior researchers for the year 2016.The Max Delbrück Prize for junior researchers is a research prize of the University of Cologne honoring outstanding research in the life and natural sciences performed within the last two years.

Maria Hermanns received the prize for her theoretical analysis of magnetic moment fractionalization arising from the interplay of frustration, topology and correlations in the context of condensed matter physics.
She has developed a family of microscopic models that allow to analytically track this fractionalization of elementary quantum degrees of freedom and to establish a rigorous connection between emergent spin liquid physics and Majorana metals.
Maria received her PhD from Stockholm University, held a postdoctoral fellowship at Princeton University, and since 2012 is a member of the Institute of Theoretical Physics where she currently leads an Emmy-Noether research group.

Emmy Noether Grant for Sabrina Disch

Sabrina Disch (Institute of Physical Chemistry) was awarded an Emmy Noether Grant by the DFG. This highly prestigious prize will allow her to build up an independent research group. In the five-year project "Dynamics of magnetization reversal and directional anisotropies in magnetic nanostructures", her group will investigate time- and spatially resolved magnetization effects in magnetic nanostructures using time-resolved, polarized neutron scattering techniques. A particular emphasis of the project will be on assemblies of orientationally aligned nanoparticles. Due to their small size, such tiny magnets obtain new dynamical properties.

Dr. Disch joined the Chemistry Department of the University of Cologne in 2014 as a junior group leader after postdoctoral stays at the University of Oregon, USA, and the Insitute Laue-Langevin in Grenoble, France. She has been a member of QM2 since 2015.

Our congratulations to Sabrina Disch!

ERC grant for Alexander Grüneis

Alexander Grüneis was awarded an ERC Consolidator grant of the European Research Council for his project "Many-body physics andsuperconductivity in 2D materials. He is a member of QM2 since April2014.

The expected duration is from 1.6.2015 - 31.5.2020.

Our congratulations to Alexander Grüneis for this important prize!

The taming of magnetic vortices

Magnetic vortex structures, so-called skyrmions, could in future store and process information very efficiently. They could also be the basis for high-frequency components. For the first time, a team of physicists succeeded in characterizing the electromagnetic properties of insulating, semiconducting and conducting skyrmion-materials and developed a unified theoretical description of their behavior. This lays the foundation for future electronic components with purpose-designed properties ... (read more)
