摘要
We study the evolution of discrete (narrow) solitons in a system of coupled Ablowitz-Ladik (AL) chains. Two types of interchain coupling are investigated: one which admits reduction of the system to the standard (integrable) AL model and one which couples opposite sites of the chains and does not admit reduction to the AL model. The condition for a perfect soliton switching between the two chains is obtained and the characteristics of the direrent couplings are analyzed.
