Exact solutions of the two-dimensional discrete nonlinear Schrodinger equation with saturable nonlinearity
Publication: Research - peer-review › Journal article – Annual report year: 2010
We show that the two-dimensional, nonlinear Schrodinger lattice with a saturable nonlinearity admits periodic and pulse-like exact solutions. We establish the general formalism for the stability considerations of these solutions and give examples of stability diagrams. Finally, we show that the effective Peierls-Nabarro barrier for the pulse-like soliton solution is zero.
