【 摘 要 】

In this paper we develop a collective coordinate approach for the dynamics of two solitons, governed by the nonlocal Gross-Pitaevskii equation (GPE). The model adequately describes both the small amplitude and large amplitude dynamics of soliton bound states (also known as soliton molecules), including the dissociation phenomena. Detailed comparison between theoretical predictions and numerical simulations of the governing GPE is presented.
