Computational symmetry hierarchy of time-reversal-even and -odd spin Hall conductivity tensors in altermagnets
Dameul Jeong, Seoung-Hun Kang, Young-Kyun Kwon
Predicting the full spin Hall conductivity tensor of a magnetic crystal is difficult because crystallographic and magnetic symmetries do not constrain all parts of the response in…
Optimizing Density Functional Theory for Strain-Dependent Magnetic Properties of Monolayer MnBiTe with Diffusion Monte Carlo
Jeonghwan Ahn, Swarnava Ghosh, Seoung-Hun Kang +6
Monolayer MnBiTe (MBT) is an intrinsically magnetic topological insulator whose magnetic response is strongly affected by strain and electron correlation. In density fu…
Magnetic and Crystal Symmetry Effects on Spin Hall Conductivity in Altermagnets
Dameul Jeong, Seoung-Hun Kang, Young-Kyun Kwon
Altermagnets, which reconcile zero net magnetization with pronounced spin splitting, offer fresh opportunities for spin-based functionalities in next-generation electronic and spin…
Optimizing Density Functional Theory for Strain-Dependent Magnetic Properties of MnBiTe with Diffusion Monte Carlo
Swarnava Ghosh, Jeonghwan Ann, Seoung-Hun Kang +6
In this study, we evaluate the predictive power of density functional theory (DFT) for the magnetic properties of MnBi\(_2\)Te\(_4\) (MBT), an intrinsically magnetic topological in…
