Modulational Instabilities and Domain Walls in Coupled Discrete Nonlinear Schrödinger Equations
arXiv:cond-mat/0409009 · doi:10.1016/j.physleta.2004.07.052
Abstract
We consider a system of two discrete nonlinear Schrödinger equations, coupled by nonlinear and linear terms. For various physically relevant cases, we derive a modulational instability criterion for plane-wave solutions. We also find and examine domain-wall solutions in the model with the linear coupling.
