Long range scattering effects on spin Hall current in -type bulk semiconductors
S. Y. Liu, Norman J. M. Horing, X. L. Lei
Employing a nonequilibrium Green's function approach, we examine the effects of long-range hole-impurity scattering on spin-Hall current in -type bulk semiconductors within the…
Qubit measurement using a quantum point contact with a quantum Langevin equation approach
Bing Dong, Norman J. M. Horing, X. L. Lei
We employ a quantum Langevin equation approach to establish non-Markovian dynamical equations, on a fully microscopic basis, to investigate the measurement of the state of a couple…
Vanishing spin-Hall current in a diffusive Rashba two-dimensional electron system: A quantum Boltzmann equation approach
S. Y. Liu, X. L. Lei, Norman J. M. Horing
We present a quantum Boltzmann equation analysis of the spin-Hall effect in a diffusive Rashba two-dimensional electron system. Within the framework of the self-consistent Born app…
Inelatic cotunneling current and shot noise of an interacting quantum dot with ferromagnetic correlations
Bing Dong, X. L. Lei, Norman J. M. Horing
We explore inelastic cotunneling through a strongly Coulomb-blockaded quantum dot attached to two ferromagnetic leads in the weak coupling limit using a generic quantum Langevin eq…
The inelastic relaxation time due to electron-electron collisions in high-mobility two-dimensional systems under microwave radiations
X. L. Lei, S. Y. Liu
In some theoretical analyses of microwave-induced magnetoresistance oscillations in high-mobility two-dimensional systems, the "inelastic relaxation time" due to electron-…
Radiation-induced magnetotransport in high-mobility two-dimensional systems: Role of electron heating
X. L. Lei, S. Y. Liu
Effects of microwave radiation on magnetoresistance are analyzed in a balance-equation scheme that covers regimes of inter- and intra-Landau level processes and takes account of ph…
A kinetic equation approach to the anomalous Hall effect in a diffusive Rashba two-dimensional electron system with magnetization
S. Y. Liu, X. L. Lei
We present a two-band kinetic equation method to investigate the anomalous Hall effect in a Rashba two-dimensional electron system subjected to a homogeneous magnetization. The ele…
Disorder effects on the spin-Hall current in a diffusive Rashba two-dimensional heavy-hole system
S. Y. Liu, X. L. Lei
We investigate the spin-Hall effect in a two-dimensional heavy-hole system with Rashba spin-orbit coupling using a nonequilibrium Green's function approach. Both the short- and lon…
Vanishing of the Dissipationless Spin Hall Effect in a Diffusive Two-Dimensional Electron Gas with Spin-Orbit Coupling
S. Y. Liu, X. L. Lei
We propose a nonequilibrium Green's function approach to study the spin-Hall effect in a two-dimensional electron system with both the Rashba and Dresselhaus spin-orbit couplings.…
