摘要

基于Gross-Pitaevskii （GP）理论中凝聚态波函数的双抛物线近似（DPA）解，研究了两种弱相互作用的玻色-爱因斯坦凝聚态（BECs）二元混合物在凝聚态吸附壁约束下的界面在偏析相中的运动特征。本文报道了当壁面的冷凝物吸附度、壁面的分离度、壁面的愈合长度和穿透深度发生变化时BECs界面的受激运动特性。我们也努力去发现界面运动特征的物理性质。

Interface’s movement in the segregated binary mixture of two weakly interacting Bose–Einstein condensates

Based on the double parabola approximation (DPA) solutions of the condensate wave functions within Gross–Pitaevskii (GP) theory, the moving feature of the interface in a binary mixture of two weakly interacting Bose–Einstein condensates (BECs) confined by the condensate adsorption wall(s) is investigated in the segregation phase. We report the excited movement properties of the BECs’ interface when the wall(s)’s condensate adsorption degree, the BECs’ separation degree, healing length, or penetration depth vary. We also make an effort to discover the physics nature of the interface’s movement feature.
