Averaging of nonlinearity-managed pulses

Research output: Contribution to journal › Article › peer-review

Abstract

We consider the nonlinear Schrödinger equation with the nonlinearity management which describes Bose-Einstein condensates under Feshbach resonance. By using an averaging theory, we derive the Hamiltonian averaged equation and compare it with other averaging methods developed for this problem. The averaged equation is used for analytical approximations of nonlinearity-managed solitons.
