Abstract

Dynamics of bright solitons are investigated by the numerical simulation in nonlinear media with varying nonlocality, and effects of the varying randomly and periodically nonlocalities on the soliton propagation and interaction are analyzed. The strong nonlocality is expanded as the fundamental nonlocality and the second-order nonlocality, and effects of the fundamental nonlocality is different from those of the second-order nonlocality. The constant nonlocality stabilizes propagation of the bright soliton if the nonlocality is strong enough, and suppresses the interaction. But the varying nonlocality leads to disintegration of the bright soliton and enhances the interaction. The effects of the varying randomly nonlocality strictly depend on the stochastic strength, and the effects of the varying periodically nonlocality become completely reliant on the period length..
