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…
Superfluid-insulator transition in a moving system of interacting bosons
E. Altman, A. Polkovnikov, E. Demler +2
We analyze stability of superfluid currents in a system of strongly interacting ultra-cold atoms in an optical lattice. We show that such a system undergoes a dynamic, irreversible…
Spin current and polarization in impure 2D electron systems with spin-orbit coupling
E. G. Mishchenko, A. V. Shytov, B. I. Halperin
We derive the transport equations for two-dimensional electron systems with spin-orbit interaction and short-range spin-independent disorder. In the limit of slow spatial variation…
