Berry-phase effects in dipole density and Mott relation
Liang Dong, Cong Xiao, Bangguo Xiong +1
We provide a unified semiclassical theory for thermoelectric responses of any observable represented by an operator that is well-defined in periodic crystals.…
Boltzmann transport from density matrix theory: interband and intraband coherences
Cong Xiao, Jihang Zhu, Bangguo Xiong
To account for the anomalous/spin Hall conductivities and spin-orbit torque in the zeroth order of electron scattering time in strongly spin-orbit coupled systems, the Boltzmann tr…
Temperature dependence of side-jump spin Hall conductivity
Cong Xiao, Yi Liu, Zhe Yuan +2
In the conventional paradigm of the spin Hall effect, the side-jump conductivity due to electron-phonon scattering is regarded to be temperature independent. To the contrary, we dr…
Conserved spin current for the Mott relation
Cong Xiao, Jihang Zhu, Bangguo Xiong +1
The conserved bulk spin current [Shi et al., Phys. Rev. Lett. 96, 076604 (2006)], defined as the time derivative of the spin displacement operator, ensures automatically the Onsage…
Boltzmann approach to spin-orbit-induced transport in effective quantum theories
Cong Xiao, Bangguo Xiong, Fei Xue
In model studies of the spin/anomalous Hall effect, effective Hamiltonians often serve as the starting point. However, a complete effective quantum theory contains not only the eff…
Boltzmann scaling of spontaneous Hall current and nonequilibrium spin-polarization
Cong Xiao, Bangguo Xiong, Fei Xue
We extend the semiclassical Boltzmann formalism for the anomalous Hall effect (AHE) in nondegenerate multiband electron systems to the spin Hall effect (SHE) and unconventional Ede…
