Nondissipative Spin Hall Effect via Quantized Edge Transport
L. Sheng, D. N. Sheng, C. S. Ting +1
The spin Hall effect in a two-dimensional electron system on honeycomb lattice with both intrinsic and Rashba spin-orbit couplings is studied numerically. Integer quantized spin Ha…
Mobility gap in fractional quantum Hall liquids: Effects of disorder and layer thickness
Xin Wan, D. N. Sheng, E. H. Rezayi +3
We study the behavior of two-dimensional electron gas in the fractional quantum Hall regime in the presence of finite layer thickness and correlated disordered potential. Generaliz…
Luttinger's Theorem and Bosonization of the Fermi Surface
F. D. M. Haldane
A course of four lectures given at the International School of Physics "Enrico Fermi", Varenna, Italy, July 1992, in which the underlying algebraic structure needed for bosonizatio…
A Geometrical Description of the "Classical" Weak-Field Hall Effect in Metals
F. D. M. Haldane
Within the ``anisotropic relaxation time'' approach to transport processes, I obtain a new geometric formula for the weak-field Hall conductivity of metals, which generalizes previ…
Spin Hall Effect and Spin Transfer in Disordered Rashba Model
D. N. Sheng, L. Sheng, Z. Y. Weng +1
Based on numerical study of the Rashba model, we show that the spin Hall conductance remains finite in the presence of disorder up to a characteristic length scale, beyond which it…
Possible Realization of Directional Optical Waveguides in Photonic Crystals with Broken Time-Reversal Symmetry
F. D. M. Haldane, S. Raghu
We show how in principle to construct analogs of quantum Hall edge states in "photonic crystals" made with non-reciprocal (Faraday-effect) media. These form "one-way waveguides" th…
