Exact solutions in coupled nonlinear Schrödinger equations with spacial inhomogeneous nonlinearity
Abstract:
Using Lie group theory we construct explicit solutions of coupled nonlinear Schrödinger systems with
spatially inhomogeneous nonlinearities. We present the general theory,
use it to show that localized nonlinearities can support bound states
with an arbitrary number of solitons. Their linear and dynamical stability
will be investigated as well as we will propose also some
applications to the field of nonlinear matter waves.
