Microwave modulation of electron temperature and Shubnikov-de Haas oscillation in two-dimensional electron systems
X. L. Lei, S. Y. Liu
Recently discovered modulations of Shubnikov-de Haas oscillations in microwave-irradiated two-dimensional electron systems are shown to arise from electron heating induced by the r…
Spin Hall Effect in a Diffusive Rashba Two-dimensional Electron Gas
S. Y. Liu, X. L. Lei
A nonequilibrium Green's functions approach to spin-Hall effect is developed in a diffusive two-dimensional electron system with Rashba spin-orbit interaction. In the presence of l…
Microwave strengths to induce magnetoresistance oscillations in high-mobility 2DES in a photon-assisted impurity scattering model
X. L. Lei
It is shown that, although the major feature of the microwave-induced magnetoresistance oscillations in two-dimensional (2D) electron systems is insensitive to the behavior of the…
Shot noise of inelastic tunneling through quantum dot systems
Bing Dong, H. L. Cui, X. L. Lei +1
We present a theoretical analysis of the effect of inelastic electron scattering on current and its fluctuations in a mesoscopic quantum dot (QD) connected to two leads, based on a…
Mesoscopic Kondo effect of a quantum dot embedded in an Aharonov-Bohm ring with intradot spin-flip scattering
Bing Dong, G. H. Ding, H. L. Cui +1
We study the Kondo effect in a quantum dot embedded in a mesoscopic ring taking into account intradot spin-flip scattering . Based on the finite- slave-boson mean-field appro…
Pumped spin-current and shot noise spectra in a single quantum dot
Bing Dong, H. L. Cui, X. L. Lei
We exploit the pumped spin-current and current noise spectra under equilibrium condition in a single quantum dot connected to two normal leads, as an electrical scheme for detectio…
Time-dependent resonant tunneling for a parallel-coupled double quantum dots
Bing Dong, Ivana Djuric, H. L. Cui +1
We derive the quantum rate equations for an Aharonov-Bohm interferometer with two vertically coupled quantum dots embedded in each of two arms by means of the nonequilibrium Green'…
Photon-Phonon-assisted tunneling through a single-molecular quantum dot
Bing Dong, H. L. Cui, X. L. Lei
Based on exactly mapping of a many-body electron-phonon interaction problem onto a one-body problem, we apply the well-established nonequilibrium Green function technique to solve…
