An MPSD theory team reports in Physical Review X that it has found no evidence of any universal topological signatures after performing the first ab initio investigation of high harmonic generation from topological insulators.
The MPSD has welcomed two new Humboldt Fellows to the Theory Department. Carlos Mauricio Bustamante and Hang Liu have each been awarded postdoctorate Humboldt Research Fellowships to carry out their own research at the Institute.
An international research team has demonstrated unambiguously that the bulk crystal Ta2NiSe5 is not an excitonic insulator, settling the debate around the microscopic origin of symmetry breaking in the material.
The electronic properties of MoSe2 are determined by the bonds of Mo and Se atoms, to which both elements contribute equally. But when exposed to ultraviolet light, the Mo signal clearly shows a signature dominated by collective processes while the Se signal suggests that the electrons act independently.
MPSD Director Angel Rubio has been elected as a member of Germany’s National Academy of Sciences, the Leopoldina. His membership will be officially bestowed upon him at a ceremony in Halle in February 2024.
Intense laser light can induce magnetism in solids on the attosecond scale – the fastest magnetic response to date. Theoreticians at the MPSD have investigated the magnetization process in several 2D and 3D materials. Their work has appeared in npj Computational Materials.
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.
An international research team led by the MPSD has found an explanation why chemical reactions are slowed down inside mirrored cavities, where molecules are forced to interact with light. Their work is a key step in understanding this experimentally observed process.
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.
