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…
Tunable Magneto-Excitonic Coupling in Alloyed van der Waals Antiferromagnet
Maciej Smiertka, Oliwia Janikowska, Katarzyna Olkowska-Pucko +18
The paper studies how adding chlorine to the van der Waals antiferromagnet CrSBr changes its electronic and excitonic properties, making excitons more localized and weakening their…
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…
Engineering photomagnetism in collinear van der Waals antiferromagnets
MengXing Na, Viktoriia Radovskaia, Dinar Khusyainov +14
Achieving efficient ultrafast optical control of antiferromagnetic spin dynamics is a central goal for next-generation high-speed THz spintronic and magnonic devices. Resonant opti…
Interplay of Quasi-Quantum Hall Effect and Coulomb Disorder in Semimetals
Ian A. Leahy, Anthony D. Rice, Jocienne N. Nelson +6
Low carrier densities in topological semimetals (TSMs) enable the exploration of novel magnetotransport in the quantum limit (QL). Recent findings consistent with 3D quasi-quantum…
