Numerical Study of Spin Hall Transport in a Two Dimensional Hole Gas System
W. Q. Chen, Z. Y. Weng, D. N. Sheng
We present a numerical study of the spin Hall effect in a two-dimensional hole gas (2DHG) system in the presence of disorder. We find that the spin Hall conductance (SHC), extrapol…
Upper Pseudogap Phase: Magnetic Characterizations
Zheng-Cheng Gu, Zheng-Yu Weng
It is proposed that the upper pseudogap phase (UPP) observed in the high-Tc cuprates correspond to the formation of spin singlet pairing under the bosonic resonating-valence-bond (…
Bosonic resonating valence bond wave function for doped Mott insulators
Z. Y. Weng, Y. Zhou, V. N. Muthukumar
We propose a new class of ground states for doped Mott insulators in the electron second-quantization representation. They are obtained from a bosonic resonating valence bond (RVB)…
Numerical Study of the Spin Hall Conductance in the Luttinger Model
W. Q. Chen, Z. Y. Weng, D. N. Sheng
We present first numerical studies of the disorder effect on the recently proposed intrinsic spin Hall conductance in a three dimensional (3D) lattice Luttinger model. The results…
Spin Hall effect in a Doped Mott Insulator
Su-Peng Kou, Xiao-Liang Qi, Zheng-Yu Weng
The existence of conserved spin Hall currents is shown in a strongly correlated system without involving spin-orbit coupling. The spin Hall conductivity is determined by intrinsic…
Mutual-Chern-Simons effective theory of doped antiferromagnets
Su-Peng Kou, Xiao-Liang Qi, Zheng-Yu Weng
A mutual-Chern-Simons Lagrangian is derived as a minimal field theory description of the phase-string model for doped antiferromagnets. Such an effective Lagrangian is shown to ret…
