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…

Unzipping flux lines from extended defects in type-II superconductors
Yariv Kafri, David R. Nelson, Anatoli Polkovnikov
With magnetic force microscopy in mind, we study the unbinding transition of individual flux lines from extended defects like columnar pins and twin planes in type II superconducto…
