Impact of exciton-phonon and exciton-magnon interaction on transport in anisotropic 2D magnetic semiconductors
Daniel Erkensten, Katarzyna Sadecka, Marie-Christin Heißenbüttel +2
Two-dimensional magnetic semiconductors provide a unique platform for exploring the interplay between charge, lattice, spin, and light. The strong Coulomb interaction combined with…
Extreme Polarization of the Optical Gap and High-Energy Exciton Landscape in CrSBr
Sayantan Patra, Sourabh Jain, Bhumika Chauhan +8
We reveal a strongly anisotropic excitonic landscape in monolayer and bulk-like CrSBr using optical absorption spectroscopy and -Bethe-Salpeter equation ca…
Coulomb Interaction in Atomically Thin Semiconductors and Density-Independent Exciton-Scattering Processes
Henry Mittenzwey, Andreas Knorr, Thorsten Deilmann
In quantum-kinetic approaches to the dynamics of Coulomb-bound many-body correlations such as excitons, trions, biexcitons or higher-order correlations, a detailed knowledge of the…
Optical Readout of Reconfigurable Layered Magnetic Domain Structure in CrSBr
Aleksandra Łopion, Pierre-Maurice Piel, Thomas Kliewer +9
The van der Waals magnetic semiconductor CrSBr combines multistable magnetic order with strong light--matter coupling, enabling optical access to a rich and reconfigurable layered…
Quadrupolar and dipolar excitons in symmetric trilayer heterostructures: Insights from first principles theory
Thorsten Deilmann, Kristian Sommer Thygesen
Excitons in van der Waals heterostructures come in many different forms. In bilayer structures, the electron and hole may be localized on the same layer or they may be separated fo…
Quadratic optical response of CrSBr controlled by spin-selective interlayer coupling
Marie-Christin Heißenbüttel, Pierre-Maurice Piel, Julian Klein +3
The optical properties of the layered magnet CrSBr are dominated by intralayer excitons: the antiferromagnetic order between the layers makes layer-to-layer charge hopping, and the…
