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…
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…
Engineering Superfluidity in Bose-Fermi Mixtures of Ultracold Atoms
D. -W. Wang, M. D. Lukin, E. Demler
We investigate many-body phase diagrams of atomic boson-fermion mixtures loaded in the two-dimensional optical lattice. Bosons mediate an attractive, finite-range interaction betwe…
Quantum information processing using localized ensembles of nuclear spins
J. M. Taylor, G. Giedke, H. Christ +5
We describe a technique for quantum information processing based on localized en sembles of nuclear spins. A qubit is identified as the presence or absence of a collective excitati…
