Spin-dependent transport through magnetic nanojunctions
Kamil Walczak, Gloria Platero
Coherent electronic transport through a molecular device is studied using non-equilibrium Green's function (NEGF) formalism. Such device is made of a carbon nanowire which is conne…
Spontaneous spin-polarized current in a nonuniform Rashba interaction system
Qing-feng Sun, X. C. Xie
We investigate the electron transport through a two-dimensional semiconductor with a nonuniform Rashba spin-orbit interaction. Due to the combination of the coherence effect and th…
Quantum transport theory for nanostructures with Rashba spin-orbital interaction
Qing-feng Sun, Jian Wang, Hong Guo
We report on a general theory for analyzing quantum transport through devices in the Metal-QD-Metal configuration where QD is a quantum dot or the device scattering region which co…
Interband electron Raman scattering in a quantum wire in a transverse magnetic field
F. M. Hashimzade, T. G. Ismailov, B. H. Mehdiyev +1
Electron Raman scattering (ERS) is investigated in a parabolic semiconductor quantum wire in a transverse magnetic field neglecting by phonon-assisted transitions. The ERS cross-se…
Semiclassical Time Evolution of the Holes from Luttinger Hamiltonian
Z. F. Jiang, R. D. Li, Shou-Cheng Zhang +1
We study the semi-classical motion of holes by exact numerical solution of the Luttinger model. The trajectories obtained for the heavy and light holes agree well with the higher o…
Resonant spin Hall conductance in quantum Hall systems lacking bulk and structural inversion symmetry
Shun-Qing Shen, Yun-Juan Bao, Michael Ma +2
Following a previous work [Shen, Ma, Xie and Zhang, Phys. Rev. Lett. 92, 256603 (2004)] on the resonant spin Hall effect, we present detailed calculations of the spin Hall conducta…
