|MATHEMATICAL PHYSICS SEMINAR|
|Topic:||Soliton Dynamics and Energy Equipartition in Inhomogeneous Media|
|Speaker:||Michael I. Weinstein|
|Date:||Wednesday, April 22|
|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.
