Spontaneous Symmetry Breaking of Solitons Trapped in a Double-Gauss Potentials
Communications in Physics
We consider an extended model of the model considered before with double-square potential, namely one-dimensional (1D) nonlinear Schrödinger equation (NLSE) with self-focusing nonlinearity and a 1D double-gauss potential. Spontaneous symmetry breaking has been presented in terms of the control parameter which is propagation constant in the case of optics and chemical potential in the of Bose-Einstein Condensate (BEC), correspondingly. The numerical simulations predict a bifurcation breaking thedoi:10.15625/0868-3166/28/4/13195 fatcat:t6hjb5wv4ne7xocturscdwxs4m
