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…

Large Magnetoresistance Induced by Quantum Charge Fluctuations in Magnetic Double Dots
L. Sheng, D. Y. Xing, D. N. Sheng
We study electron tunneling through two small ferromagnetic dots. Quantum charge fluctuations and interdot coupling make each Coulomb peak of the conductance at zero interdot coupl…

Quantum Hall effect at weak magnetic field: New float-up picture
D. N. Sheng, Z. Y. Weng, X. G. Wen
The fate of integer quantum Hall effect (IQHE) at weak magnetic field is studied numerically in the presence of {\it correlated} disorders. We find a systematic {\it float-up} and…
