Angel Rubio, the Director of the MPSD’s Theory Department and the Institute’s Managing Director, has been named as a Highly Cited Researcher 2022 by Clarivate. His papers rank in the top 1 per cent by citations in this research field.
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.
