Scattering-induced splitting of solitons in the discrete NLS equation with saturable nonlinearity

J. F. Tsoplefack, F. Palmero, J. Cuevas-Maraver +2

We study systematically the scattering of solitons on localized impurities in the discrete nonlinear Schrödinger (DNLS) equation with a saturable nonlinearity. We show that, apart…
