在原子玻色-爱因斯坦凝聚体中产生无序涡旋阵列的方法

A method to create disordered vortex arrays in atomic Bose-Einstein condensates

Eniko J. M. Madarassy

摘要:

提出了一种在囚禁原子玻色-爱因斯坦凝聚体中产生湍流的方法。通过用其复共轭Psi^{*}代替我们盒子上半部分的波函数Psi,新的负涡旋被引入系统。通过求解二维Gross-Pitaevskii方程(2D GPE)进行模拟。我们通过监测密度和相位剖面的演化来研究波函数的连续动力学。

英文摘要:

We suggest a method to create turbulence in a trapped atomic Bose-Einstein condensate (BEC). By replacing in the upper half part of our box the wave function, Psi, with its complex conjugate, Psi^{*}, new negative vortices are introduced into the system. The simulations are performed by solving the two-dimensional Gross-Pitaevskii equation (2D GPE). We study the successive dynamics of the wave function by monitoring the evolution of density and phase profile.
