Lattice solitons in quasicondensates
arXiv:cond-mat/0410323 · doi:10.1103/PhysRevLett.94.130403
Abstract
We analyze finite temperature effects in the generation of bright solitons in condensates in optical lattices. We show that even in the presence of strong phase fluctuations solitonic structures with well defined phase profile can be created. We propose a novel family of variational functions which describe well the properties of these solitons and account for the non-linear effects in the band structure. We discuss also the mobility and collisions of these localized wave packets.
