Edge Spin Current and Spin Polarization in Quantum Hall Regime
Yun-Juan Bao, Huai-Bing Zhuang, Shun-Qing Shen +1
We study the edge spin current and spin polarization in a two-dimensional electron gas with spin-orbit coupling in the presence of a perpendicular magnetic field. The edge effect r…
Dynamically generated dimension reduction and crossover in a spin orbital model
Theja. N. De Silva, Michael Ma, Fu Chun Zhang
We study a spin orbital model in which the spin-spin interaction couples linearly to the orbital isospin. Fluctuations drive the transition from paramagnetic state to C type ordere…
Resonant Spin Hall Conductance in Two-Dimensional Electron Systems with Rashba Interaction in a Perpendicular Magnetic Field
Shun-Qing Shen, Michael Ma, X. C. Xie +1
We study transport properties of a two-dimensional electron system with Rashba spin-orbit coupling in a perpendicular magnetic field. The spin orbit coupling competes with Zeeman s…
Theory for spin and orbital orderings in high temperature phase in
Theja N. De Silva, Anuvrat Joshi, Michael Ma +1
Motivated by the recent neutron diffraction experiment on , we consider a microscopic model where each ion is occupied by two 3d electrons of parallel spins with tw…
Theory of Excitons in Insulating Cu-Oxide Plane
Fu Chun Zhang, Kwai-Kong Ng
We use a local model to study the formation and the structure of the low energy charge transfer excitations in the insulating Cu-O plane. The elementary excitation is a bound e…
