玻色-爱因斯坦凝聚体的非线性薛定谔方程

Nonlinear Schrödinger Equations for Bose-Einstein Condensates

Luigi Galati, Shijun Zheng

摘要:

Gross-Pitaevskii方程,或者更一般的非线性薛定谔方程,模拟了超低温下宏观气态超流波物质态的玻色-爱因斯坦凝聚体。我们提供了分析研究的NLS与$L^2$的初始数据,以了解传播的散焦和聚焦波的BEC机制中存在的电磁场。对具有各向异性二次势的二维GPE进行了数值模拟。

英文摘要:

The Gross-Pitaevskii equation, or more generally the nonlinear Schrödinger equation, models the Bose-Einstein condensates in a macroscopic gaseous superfluid wave-matter state in ultra-cold temperature. We provide analytical study of the NLS with $L^2$ initial data in order to understand propagation of the defocusing and focusing waves for the BEC mechanism in the presence of electromagnetic fields. Numerical simulations are performed for the two-dimensional GPE with anisotropic quadratic potentials.
