Abstract: In this work, we consider a nonlinear Schrödinger equation with stimulated Raman scattering and quintic nonlinearity, which works as a model for the propagation of ultrashort pulse in optical fiber and also corresponds to one-dimensional… read more here.

Abstract: We investigate numerically the stability and evolution of two-dimensional soliton-like structures in the form of necklaces in media with cubic-quintic nonlinearity. Using a variational technique, optimal input propagation parameters for the long-lived stable solutions are… read more here.

Abstract: Abstract Exact expressions are obtained for stationary periodic waves in cubic-quintic nonlinear media with opposite signs of nonlinearity. It is shown that defocussing/focussing quintic nonlinearity can lead to stabilization of snoidal/(cnoidal and dnoidal) periodic waves… read more here.

Abstract: Abstract In this paper, we discover several new soliton families in the PT symmetric optical lattices with the nonlocal competing cubic–quintic nonlinearity, and investigate their existence and stability ranges. We detailedly study the influence of… read more here.
