Tutors wanted
For the winter semester 2023/24, we are again looking for HiWis and doctoral students who, for example, supervise exercise groups or internships as tutors. Numerous positions are advertised. Apply here.
The analysis of the universe
The European Southern Observatory (ESO) has signed an agreement with an international consortium of institutions to develop and build ANDES, the ArmazoNes High Dispersion Echelle Spectrograph. The ANDES instrument will be installed on ESO's Extremely Large Telescope (ELT). The scientific objectives are to search for signs of life on exoplanets, identify the first stars, test variations in the fundamental constants of physics and measure the acceleration of the expansion of the universe. The Institute of Astrophysics and Geophysics at the University of Göttingen is also involved in this project.
Quantum electronics: Charge travels like light in bilayer graphene
An international research team led by the University of Göttingen has demonstrated experimentally that electrons in naturally occurring double-layer graphene move like particles without any mass, in the same way that light travels. Furthermore, they have shown that the current can be “switched” on and off, which has potential for developing tiny, energy-efficient transistors – like the light switch in your house but at a nanoscale.
Young Scientist Award for Professor Viola Priesemann
During this year's spring conference of the German Physical Society (DPG), Professor Viola Priesemann received the Young Scientist Award for Socio- and Econophysics. The physicist conducts research at the Max Planck Institute for Dynamics and Self-Organization and the University of Göttingen. The prize is endowed with 7,500 euros and honors her work on propagation processes in complex systems.
Long-period oscillations control the Sun’s differential rotation
The interior of the Sun does not rotate at the same rate at all latitudes. The physical origin of this differential rotation is not fully understood. A team of scientists at the Max Planck Institute for Solar System Research (MPS) in Germany has made a ground-breaking discovery. As the team reports today in the journal Science Advances, the long-period solar oscillations discovered by MPS scientists in 2021 play a crucial role in controlling the Sun’s rotational pattern.
MSCA postdoctoral fellowship for Dr. Pallavi Kumari
The European Commission has selected Dr. Pallavi Kumari for a two-year postdoctoral fellowship in the framework of the Marie Skłodowska-Curie Actions (MSCA) to work at the University of Göttingen starting in 2024. She will work with Prof. Dr. Sarah Köster at the Institute for X-Ray Physics, Faculty of Physics. Her research will focus on cell mechanics and in particular investigate the origin of stretchability in vimentin intermediate filaments and their direct interaction with actin filaments at the single filament level using state-of-the-art biophysical techniques.
How electron spectroscopy measures exciton “holes”
Semiconductors are ubiquitous in modern technology, working to either enable or prevent the flow of electricity. In order to understand the potential of two-dimensional semiconductors for future computer and photovoltaic technologies, researchers from the Universities of Göttingen, Marburg and Cambridge investigated the bond that builds between the electrons and holes contained in these materials. By using a special method to break up the bond between electrons and holes, they were able to gain a microscopic insight into charge transfer processes across a semiconductor interface.
Unexpected curveball in miniature
Whether you are familiar with the term “Magnus effect” or not, you have certainly seen it in action. It is when a spinning ball – for instance in football, cricket or baseball – bends away from its expected trajectory, often to the surprise of the opposing team. The principle also has engineering uses, for example to propel certain types of ships or aircraft using a “Flettner rotor”. Physicists have now demonstrated that the Magnus effect also exists at a microscopic level, where its effects can become really significant under certain conditions.
Majority rule in complex mixtures
The very first life on earth is thought to have developed from “protocells” – liquid mixtures of many different types of molecules. Researchers from the University of Göttingen have now shown that in such mixtures, small imbalances in the number of molecules of different types can have an unexpected effect. A surprising interplay with the complex pattern of interactions strongly amplifies such imbalances – meaning that a type of molecule that is only slightly in the majority can almost entirely separate out from the others. These fundamental findings point towards a new mechanism that will apply in many complex mixtures.
