Terahertz light pulses can stabilize ferromagnetism in YTiO3 at temperatures more than three times its usual transition temperature. Researchers from the Cavalleri group report in Nature that the high-temperature ferromagnetic state persisted for many nanoseconds after the light exposure.
Wiebke Kohlbrecher (20) has spent five weeks at the MPSD to learn at first hand about the day-to-day work of its researchers. She will complete three internships in total as part of the Hamburg-based ProTechnicale program which offers female school leavers an orientation year in STEM (Science, Technology, Engineering and Maths) occupations.
Researchers in Germany and the U.S.A. propose a new optical method to verify topological magnon phases. Writing in PRL, the team shows that the intensity of polarized laser light scattered back from a magnetic material is an indicator of topological phases.
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.
