Stabilization and destabilization of second-order solitons against perturbations in the nonlinear Schrödinger equation
Stabilization and destabilization of second-order solitons against perturbations in the nonlinear Schrödinger equation
We consider splitting and stabilization of second-order solitons (2-soliton breathers) in a model based on the nonlinear Schrodinger equation, which includes a small quintic term, and weak resonant nonlinearity management (NLM), i.e., time-periodic modulation of the cubic coefficient, at the frequency close to that of shape oscillations of the 2-soliton. …
