An exact treatment for the BEC with three-body recombination and time-dependent scattering length

Abstract

In this study, Gross-Pitaevskii (GP) equation with three-body recombination and with a time-dependent scattering length is investigated. It is shown that GP equation admits an exact solution for a special choice of the time-dependent scattering length. The effect of Feshbach resonance on the collapse dynamics is investigated for large vertical bar a vertical bar for which the three body recombination rate K-3 grows with a(4) (C) 2006 Elsevier Inc.
