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…

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…
