Influence of nonlocalization degree on the interaction between spatial dark solitons

摘要: 对1＋1维非局域自散焦介质中暗孤子的相互作用进行了研究.数值模拟结果表明：在非局域自散焦介质中,存在着暗孤子相互作用的临界点.在临界点上,吸引力等于排斥力;在临界点外,暗孤子间相互作用可能表现为相互吸引也可能表现为相互排斥.

Abstract: The interaction between dark solitons in nonlocal self-defocusing media is investigated.Numerical results show that there is a critical condition for interaction between dark solitons in nonlocal self-defocusing medium.Under the critical condition,dark solitons will neither attract nor repell each other because the attractive force and repulsive force between them are identical.Beyound the critical condition,dark solitons may attract or repell each other depending on the nonlocalization degree and distance between them.The value of the critical condition is found.
