Unconventional and Fragile Magnetic Exciton in a van der Waals Quantum Magnet
Kai-Xuan Zhang, Min Zhang, Minjae Kim +25
The study investigates a magnetic exciton in the van der Waals antiferromagnet NiPS3, showing that its sharp, optically bright emission is quickly quenched by modest hydrostatic pr…
Agentic multi-fidelity learning of quasiparticle and excitonic properties
Arnab Neogi, Aaron Forde, Christopher A. Lane +2
Many-body GW-Bethe-Salpeter equation calculations are essential for accurate simulations of electronic structure and optical properties in modern low-dimensional nanomaterials. How…
Competing Magnetic Ground States in Copper-Doped PbPO
Lin Hou, Kevin Allen, Christopher Lane +1
We investigate the electronic and magnetic properties of copper-doped Pb(PO)O using a combination of density functional theory and many-body perturbation theory. The…
Atomically-sharp magnetic soliton in the square-net lattice EuRhAlSi
Kevin Allen, Juba Bouaziz, Yichen Zhang +17
Topological spin textures are hallmark manifestations of competing interactions in magnetic matter. Their effective description by nonlinear field theories reflects an energetic fr…
Effect of Electron Correlation on the Integer Quantum Hall Effect
Daniel Staros, Christopher Lane, Roxanne Tutchton +1
We numerically investigate the effect of electron correlation on the integer quantum Hall effect in a square lattice. Increasing the correlation strength via the effective onsite r…
Quantum oscillations and anisotropic magnetoresistance in the quasi-two-dimensional Dirac nodal line superconductor
Yuxiang Gao, Kevin Allen, Rose Albu Mustaf +8
Recent interest in quantum materials has focused on systems exhibiting both superconductivity and non-trivial band topology as material candidates to realize topological or unconve…
