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.
An MPSD theory team describes in PNAS how high harmonics can illuminate the movement of atoms and electrons down to a few femtoseconds. As the high harmonics change in intensity, they provide ‘snapshots’ of the atoms’ and electrons’ movements at each exact moment.
Excitons whose electrons have a 1D character while the holes display 2D characteristics have been produced in layered SiP2 for the first time. The study by experimentalists at two Chinese Universities and theoreticians at the MPSD has appeared in Nature Materials.
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.
Condensed matter physicist Ajit Srivastava, an Associate Professor at Emory University in the United States, has been awarded a prestigious ERC Consolidator Grant to carry out research at the MPSD for the next five years.
Dr. José J. Baldoví, a former member of the MPSD's Theory Department and now a distinguished researcher from the Gen-T Excellence Program of the Generalitat Valenciana in the Institute of Molecular Science (ICMol) of the University of València, has been awarded an ERC Starting Grant.
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.
The Alexander von Humboldt Foundation has awarded a Research Fellowship to I-Te Lu, who will study light-matter interaction using Quantum Electrodynamics Density Functional Theory (QEDFT) in Angel Rubio’s group at the MPSD.
