| One of the most interesting phenomena revealed in the experiments with optical lattices is the interference between the condensates formed independently in the disconnected potential wells [Z.Hadzibabic, et al., PRL 93, 180403 (2004)]; a similar effect was observed also in the multi-Josephson-junction loops [R.Carmi et al., PRL 84, 4966 (2000)]. The aim of the present report is to show that such coherence between the independently-formed Bose condensates leads also to the profound consequences for the strongly nonequilibrium phase transformations in the condensed-matter systems. In particular, it enables us to explain the experimental data on the concentration of topological defects (vortices) quenched in the superfluids and superconductors, which was measured to be substantially less than the earlier theoretical predictions [e.g. M.E.Dodd et al., PRL 81, 3703 (1998)]. |
