Spin Liquid Phase in Anisotropic Triangular Lattice Heisenberg Model: Exact diagonalization and density-matrix renormalization group calculations
M. Q. Weng, D. N. Sheng, Z. Y. Weng +1
Based on exact diagonalization and density matrix renormalization group (DMRG) method, we show that an anisotropic triangle lattice Heisenberg spin model has three distinct quantum…
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…
