Anomalous Hall and Nernst effects driven by static and fluctuating spin chiralities on Kagome lattice

H. B. Li, Z G Zhu, Gang Su

We theoretically investigate the anomalous Hall and Nernst effects (AHE and ANE) in a two dimensional Kagome lattice to uncover the distinct roles of static and fluctuating scalar spin chi ralities. Employing Monte Carlo simulations incorporating with a tight binding Hamiltonian via …

Electro-optic Kerr effect induced by nonlinear transport in monolayer WTe 2

H. B. Li, Zhen‐Gang Zhu, Gang Su

The nonlinear Hall effect (NLHE) can induce optical anisotropy by modifying a material's dielectric tensor, presenting opportunities for novel characterization and device applications. While the magneto-optical Kerr effect (MOKE) probes the linear Hall effect (LHE) in magnetic materials, an analogous optical probe …
