摘要
研究了盘状势阱中二维玻色-爱因斯坦凝聚(BEC)的孤立波.在平均场理论下,由BEC所满足的Gross-Pitaevkii方程出发导出了二维BEC所满足的非线性Schrdinger方程.从该方程出发,研究单组分常振幅二维BEC(单组分常振幅BEC)的调制不稳定性,得到了该系统相应的增长率.
The solition wave in Bose-Einstein condensate with disk-shaped trap is investigated in this paper. Beyond the mean field, a two- dimensional nonlinear Schr6dinger equation is obtained. The modulational instability for this system is studied analytically, and the growth rate for it is given.
