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.
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.
Predictions of how light interacts with real materials can consume vast computing resources. By reshaping the equation so that some quantum light is integrated in the matter component from the outset, scientists have developed a far more efficient approach.
Twister bilayer MoS2 can be used to control kinetic energy scales in solids. Researchers have shown that the electrons in MoS2 can interfere destructively, stopping their motion for certain paths. Combined with the twist this makes it possible to engineer exotic magnetic states.
Researchers in Hamburg and Aachen suggest a surprising connection between the nematic behavior of a superconductor in a magnetic field — a state that resembles liquid crystals used in LCDs — and its spiral-like groundstate in the absence of the field.
Photons trapped in a cavity can cause a crystal known as Strontium Titanate (SrTiO3) to become ferroelectric, according to a new study by the MPSD’s Theory group. The findings have been published in PNAS.
Researchers have watched in real time how molecules move during singlet exciton fission, an important process in light-based technologies. They observed the movements in single crystals comprised of pentacene molecules, showing that a collective motion of molecules may be the origin of the fast timescales connected to this process.
MPSD and MIT researchers predict that light trapped in a cavity can be used to create a new kind of particle in a solid, consisting of three components at once: Light (photons), electronic excitations (excitons) and lattice vibrations (phonons).
