Intrinsic Spin Hall Effect: Topological Transitions in Two-Dimensional Systems
arXiv:0706.2482 · doi:10.1103/PhysRevLett.99.236804
Abstract
The spin-Hall conductivity in spatially-homogeneous two-dimensional electron systems described by the spin-orbit Hamiltonian \hbar Ω_p σis presented as a sum of the universal part Me/8 π\hbar determined by the Berry phase Φ=M π(M is an odd integer, the winding number of the vector Ω_p) and a non-universal part which vanishes under certain conditions determined by the analytical properties of Ω_p. The analysis reveals a rich and complicated behavior of the spin-Hall conductivity which is relevant to both electron and hole states in quantum wells and can be detected in experiments.
