Spatial disorder of soliton solutions for 2D nonlinear Schrödinger lattices

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

In this paper, we employ the construction of topological horseshoes to study the pattern of the soliton solutions to the discrete nonlinear Schrödinger (DNLS) equations in a twodimensional lattice. The spatial disorder of the DNLS equations is the result of the strong amplitudes and stiffness of the nonlinearities. The complexity of this disorder is determined by the oscillations (number of turning points) of the nonlinearities. Nonnegative soliton solutions of the DNLS equations with a cubic nonlinearity is also discussed.
