Small-angle impurity scattering and the spin Hall conductivity in 2D systems
A. V. Shytov, E. G. Mishchenko, H. -A. Engel +1
An arbitrarily small concentration of impurities can affect the spin Hall conductivity in a two-dimensional semiconductor system. We develop a Boltzmann-like equation that can be u…
Spin-charge separation and localization in one-dimension
O. M. Auslaender, H. Steinberg, A. Yacoby +5
We report on measurements of quantum many-body modes in ballistic wires and their dependence on Coulomb interactions, obtained from tunneling between two parallel wires in a GaAs/A…
Theory of Spin Hall conductivity in n-doped GaAs
Hans-Andreas Engel, Bertrand I. Halperin, Emmanuel I. Rashba
We develop a theory of extrinsic spin currents in semiconductors, resulting from spin-orbit coupling at charged scatterers, which leads to skew scattering and side jump contributio…
Decay of super-currents in condensates in optical lattices
A. Polkovnikov, E. Altman, E. Demler +2
In this paper we discuss decay of superfluid currents in boson lattice systems due to quantum tunneling and thermal activation mechanisms. We derive asymptotic expressions for the…
Theory of momentum resolved tunneling into a short quantum wire
Gregory A. Fiete, Jiang Qian, Yaroslav Tserkovnyak +1
Motivated by recent tunneling experiments in the parallel wire geometry, we calculate results for momentum resolved tunneling into a short one-dimensional wire, containing a small…
Decay of a superfluid currents in a moving system of strongly interacting bosons
A. Polkovnikov, E. Altman, E. Demler +2
We analyze the stability and decay of supercurrents of strongly interacting bosons on optical lattices. At the mean field level, the system undergoes an irreversible dynamic phase…
