MPSD research group leader James McIver, who is also an Assistant Professor of Physics at Columbia University in New York, has been awarded the prestigious Early Career Award by the U.S. Department of Energy (DOE).
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.
Plasmons promise a variety of applications if the processes triggered by optical excitation in the nanoparticles can be controlled. A research team from Hamburg and Berlin reports in Nano Letters experimental observations that cannot be explained by established models and describes a new theoretical model that explains the dynamics of excited gold nanoparticles observed in experiments.
MPSD researchers report in PNAS how they observed liquid glycerol in a completely unexpected rubbery state. The rapidly expanding bubbles on the surface of the liquid in vacuum, created by a pulsed laser did not behave like a viscous liquid but like the elastic envelope of a rubber toy balloon.
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.
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.
How long does it take electrons to ‘dress’ in light and form Floquet bands? Just one single optical cycle is enough, according to a research team involving the Universities of Marburg, Regensburg and MPSD group leader Michael Sentef. Its study has been published in Nature.
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.
