Dynamics of bound vector solitons induced by stochastic perturbations: soliton breakup and soliton switching
The paper addresses dynamics of two-component solitons in the system of nonlinearily coupled nonlinear Schrödinger (NLS) equations of the Manakov's type, i.e., with equal cross- and self-phase-modulation coefficients. The aim is to study splitting and switching of the two-component solitons under the action of random perturbations of two different types: a random term in initial conditions, or a random term added to the dispersion coefficient in each equation. Results are produced by means of direct simulations. They are also compared with similar results obtained in nonintegrable versions of the system of coupled NLS equations.
