Abstract

我们与驱散在雪茄烟形状的 Bose 爱因斯坦冷凝物讨论原子事波浪的可能的非线性的波浪。波浪能被一个 KdV 类型方程描述。KdV 类型方程有一个独居的波浪答案。波浪的振幅,速度,和宽度与时间 t 指数地变化。γ 的消散的术语为波浪振幅,速度,和宽度起一个重要作用。比较在分析答案和数字结果之间被给了。两个在好同意,这被显示出。

Nonlinear Waves in a Cigar-Shaped Bose–Einstein Condensate with Dissipation

Yang Xiao-Xian, Yu-Ren Shi, Duan Wen-Shan

We discuss the possible nonlinear waves of atomic matter waves in a cigar-shaped Bose-Einstein condensate with dissipation. The waves can be described by a KdV-type equation. The KdV-type equation has a solitary wave solution. The amplitude, speed, and width of the wave vary exponentially with time t . The dissipative term of γ plays an important role for the wave amplitude, speed, and width. Comparisons have been given between the analytical solutions and the numerical results. It is shown that both are in good agreement.
