Abstract: Competing nonlinearities, such as the cubic (Kerr) and quintic nonlinear terms whose strengths are of opposite signs (the coefficients in front of the nonlinearities), exist in various physical media (in particular, in optical and matter-wave… read more here.

Abstract: Abstract The dynamical stability properties of gap solitons in a quasi-one-dimensional Bose–Einstein Condensate (BEC) loaded in a Jacobian elliptic sine potential are investigated numerically. The Gross–Pitaevskii equation (GPE) is adopted to describe the dynamical behaviors… read more here.

Abstract: We show that dark spatial gap solitons can occur inside the band gap of an exciton-polariton condensate (EPC) in a one-dimensional periodic potential. The energy dispersions of an EPC loaded into a periodic potential show… read more here.

Abstract: This paper numerically investigates the evolution of solitons in an optical lattice with gradual longitudinal manipulation. We find that the stationary solutions (with added noise to the amplitude) keep their width, profile, and intensity very… read more here.
