Time/Room: | 4:00pm - 5:00pm/S-101 |

We discuss the dynamics of soliton-like solutions of the nonlinear Schroedinger-Gross Pitaevskii equation. After a review of basic results, we outline recent work on the large time energy distribution in multimoded systems and on gap-solitons, localized states with frequencies in spectral gaps associated with a background periodic potential.
