摘要：
The collision dynamics of two solitonlike localized excitations in a nonintegrable discrete (1 x 1)-dimensional nonlinear Schrodinger system is studied numerically. It is demonstrated that the collision dynamics exhibits a complicated resonance structure of interlacing bound-state regions and escape regions of localized excitations with a sensitive dependence on the incoming energies of the localized excitations. We emphasize that this resonance is a combined effect of discreteness and nonintegrability of the system and contrast it with topological kink-antikink collisions in phi(4) and related systems.
