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. more

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. more

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. more

Theoreticians at the MPSD predict that a unique laser source could produce highly controllable electric currents in any bulk material. The team’s work has been published in PRL. more

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. more

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. more

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. more

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). more

An international research team has demonstrated that ultrashort laser pulses can be used to protect one of the DNA building blocks against destruction induced by vacuum ultraviolet (VUV) radiation. A second infrared laser flash prevented the adenine molecule from disintegrating. more

Researchers from the MPSD and UNIST in South Korea have discovered that the existing method to calculate the Mott insulating state in 1T-TaS2 is flawed. The team suggests a different approach instead to calculate electron "traffic jams". more
