Exciton-Polariton scattering for defect detection in cold atom Optical Lattices

open access: yes, 2007
We study the effect of defects in the Mott insulator phase of ultracold atoms in an optical lattice on the dynamics of resonant excitations. Defects, which can either be empty sites in a Mott insulator state with one atom per site or a singly occupied ...

Macroscopic quantum tunneling in "small" Josephson junctions in magnetic field

open access: yes, 2007
We study the phenomenon of macroscopic quantum tunneling (MQT) in small Josephson junctions (JJ) with an externally applied magnetic field. The latter results in the appearance of the Fraunhofer type modulation of the current density along the barrier ...
