Localized Excitons and Exciton-Phonon Coupling in Antiferromagnetic AgCrP2S6
Jessica McDivitt, Dimitar Pashov, Mark van Schilfgaarde +4
AgCrP2S6 combines a low-symmetry thiophosphate framework with an antiferromagnetic Cr sublattice and nonmagnetic Ag sites, providing a setting in which covalency and magnetic local…
Manipulation of localized excitons in CrPS by temperature and magnetic field
Dipankar Jana, Swagata Acharya, Amit Pawbake +9
Layered van der Waals magnetic semiconductors provide a versatile platform for exploring excitonic phenomena intertwined with spin and lattice degrees of freedom, enabling excitons…
Magnetic exchange interactions in the molecular orbital spin system NaV2O5 from a distributed moment point of view
Claudio Garcia, Ilteris K. Turan, Swagata Acharya +3
The magnetism in NaV2O5 results from doping of the narrow split-off conduction band of V2O5, which becomes half-filled and leads to a Mott-insulating splitting of spin resolved ban…
Tunable Magneto-Excitonic Coupling in Alloyed van der Waals Antiferromagnet
Maciej Smiertka, Oliwia Janikowska, Katarzyna Olkowska-Pucko +18
The unique coupling between magnetic order and photo-generated excitons, electron-hole pairs bound by Coulomb interaction, in layered magnetic semiconductors offers a powerful mech…
Bright and Dark Excitons in CrSBr: Local Ligand-Field Character and Band-Coherent Optical Selection Rules
Swagata Acharya, Jessica McDivitt, Dimitar Pashov +3
Magnetic van der Waals semiconductors such as CrSBr host an intricate exciton landscape whose physical interpretation has converged only recently. A many-body Feynman diagrammatic…
Bond, orbital and spin order in d4/d6/d7 perovskite oxides: successes and limitations of foundation interatomic potentials
Swagata Acharya, Dimitar Pashov, Mark van Schilfgaarde +1
Foundation machine-learning interatomic potentials (MLIPs) are rapidly replacing density-functional theory (DFT) for modeling structure and nuclear dynamics, making their fidelity…
