Researchers from the Cavalleri group report in PNAS that superconducting ‘stripes’ in certain copper-based compounds may lead to a break in the material’s crystal symmetry, thus resulting in anomalous emission of terahertz radiation.
Kateryna Kusyak, a PhD student in James McIver’s research group at the MPSD, has been honored with the Jean-Marie Lehn and Klaus von Klitzing Prize for the best Master’s thesis in Nanoscience in the winter semester 2021/22.
Felix Sturm, a Master student in the MPSD research group Ultrafast Transport in Quantum Materials, has been honored for obtaining the best Bachelor degree in Nanosciences at the University of Hamburg 2021/22.
Hope Bretscher from the Ultrafast Transport in Quantum Materials research group has been selected for a Marie Skłodowska-Curie Actions Fellowship. She will investigate the behavior of electrons in materials made up of stacked layers that are each just a few atoms thick.
A new supercomputer capable of handling highly data-intensive calculations for the MPSDand the MPI for the Physics of Complex Systems (MPIPKS) has gone online. Computations which would previously have taken two to three weeks can now be carried out within a single day.
Jérôme Faist, Professor at the Institute for Quantum Electronics at ETH Zürich, has been awarded a Humboldt Prize to pursue his work at the MPSD in Hamburg. His research centers on the fluctuating fields found in a vacuum and how these could be controlled.
Researchers in Hamburg have discovered that the ferroelectric polarization of lithium niobate (LiNbO3) changes in areas well away from the direct ‘hit’ of a laser pulse, with the polarization reversal occurring throughout the entire crystal. The team’s study of this hitherto unknown phenomenon - called nonlocal nonlinear phononics - has been published in Nature Physics.
Hope Bretscher from the Ultrafast Transport in Quantum Materials Group based at the MPSD has been selected for a postdoctoral Research Fellowship by the Alexander von Humboldt Foundation. She currently investigates graphene heterostructures using on-chip THz spectroscopy.
Jie Shan, Professor of Applied and Engineering Physics and Physics at Cornell University (USA), and Prineha Narang, Assistant Professor of Computational Materials Science at Harvard University (USA) and currently on a research stay at the MPSD, will be awarded the Mildred Dresselhaus Prize 2021.
Research team involving experimentalists and theorists explores how light can fundamentally alter the properties of solids - and how to harness these phenomena in laser-driven materials for future applications. Their colloquium has been published in Reviews of Modern Physics.
