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…

Andreev Peaks and Massive Magnons in Cuprate SNS junctions
Assa Auerbach, Ehud Altman
The projected SO(5) theory (pSO(5)) is used to resolve the puzzle of two distinct energy gaps in high T Superconductor-Normal-Superconductor junctions. Counter to conventional…
