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…
Shiba multiplets due to Mn impurities in MgB_2
Catalin Pascu Moca, Gergely Zarand, Eugene Demler +1
We study the effect of magnetic Mn ions on the two-band superconductor MgB_2, and compute both the total and spin resolved scanning tunneling spectrum in the vicinity of the magnet…
Fermions and Bosons in Superconducting Amorphous Wires
Yuval Oreg, Eugene Demler
We discuss the destruction of superconductivity in quasi-one-dimensional systems due to the interplay between disorder and Coulomb repulsion. We argue that to understand the behavi…
Topological doping and the stability of stripe phases
Leonid P. Pryadko, Steven A. Kivelson, V. J. Emery +2
We analyze the properties of a general Ginzburg-Landau free energy with competing order parameters, long-range interactions, and global constraints (e.g., a fixed value of a total…
