准一维偶极玻色-爱因斯坦凝聚体中的亮孤子
Bright Solitons in Dipole Bose-Einstein Condensates
-
摘要: 通过变分法分析,发现排斥短程相互作用的准一维BEC是不存在亮孤子的,但是当长程的偶极相互作用存在时,两者的相互影响导致了准一维BEC凝聚体中稳定的亮孤子的产生.另外,当偶极相互作用过大时,又会破坏孤子.Abstract: The bright solitons in quai-1D dipole BECs were analyzed with the variational analysis.These solitons didn t exist in short-range interacting BECs,but present in dipole BECs,and they will vanish at large dipole-diplole interactions.
