Özet

Wave collapse is arrested in the self-focusing nonlinear Schrodinger equation with coupling to a mean term (NLSM) by adding an external potential (lattice) to the governing equation. It is numerically demonstrated that collapse will eventually occur in a lattice-free system and it can be suppressed by adding an external periodic lattice to the governing system. It is numerically shown that lattice depth provides great controllability on soliton stability and more robust solitons can be obtained. (C) 2016 Elsevier BY. All rights reserved.
