排斥势中随时间变化原子间相互作用的玻色-爱因斯坦凝聚的亮孤子的动力学

Dynamics of a bright soliton in Bose-Einstein condensates with time-dependent atomic scattering length in an expulsive parabolic potential

简要地介绍了玻色-爱因斯坦凝聚现象及国际学术界的实验研究动态和最近的一项理论研究进展.给出了一个一维非线性薛定谔方程的严格解,它描述了在一个排斥势中随时间变化的原子间相互作用的玻色-爱因斯坦凝聚的一个亮孤子的动力学.

Bose-Einstein condensates are introduced briefly, together with experimental progresses and a recent theoretical work. A family of exact solutions of the one-dimensional nonlinear Schrdinger equation is derived, which describes the dynamics of a bright soliton in Bose-Einstein condensates with the time-dependent interatomic interaction in an expulsive parabolic potential.
