Intrinsic orbital and spin Hall effect in bismuth semimetal
Guanxiong Qu, Gen Tatara
We investigate the intrinsic orbital Hall conductivity (OHC) and spin Hall conductivity (SHC) in a bismuth semimetal, by employing an sp-orbital tight-binding model. We report a no…

Spin Hall effect driven by the spin magnetic moment current in Dirac materials
Zhendong Chi, Guanxiong Qu, Yong-Chang Lau +5
The spin Hall effect of a Dirac Hamiltonian system is studied using semiclassical analyses and the Kubo formula. In this system, the spin Hall conductivity is dependent on the defi…

Inverse Faraday effect in massive Dirac electrons
Guanxiong Qu, Gen Tatara
We study the inverse Faraday effect (IFE) in a Dirac Hamiltonian with random impurities using Keldysh formalism and diagrammatic perturbation theory. The mass term in the Dirac Ham…
