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.
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.
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.
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.
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.
