标题： Nucleation line in three-component Bose-Einstein condensates in Gross-Pitaevskii theory

摘要： 通过Gross-Pitaevskii理论，我们研究了在组分1和2之间强分离情况下，三组分玻色-爱因斯坦凝聚体中润湿相变的可能性。第三组分起到表面活性剂的作用，可以润湿由组分1和2形成的界面。研究了组分1和2对称的情况下的成核线方程和润湿相图。通过对三个耦合的Gross-Pitaevskii方程进行线性化，得到了各组分的波函数。提出了预润湿相中表面活性剂厚度的解析近似。结果表明，预润湿相中的表面活性剂厚度在对数尺度上与化学势比值呈线性变化。 显示英文摘要

摘要： By means of Gross-Pitaevskii theory we investigate the possibility of wetting phase transition in three-component Bose-Einstein condensates within the strong segregation between components 1 and 2. Third component plays the role of a surfactant, which can wet the interface formed by components 1 and 2. The case of symmetry of components 1 and 2, the equation for nucleation line and wetting phase diagram are studied. By linearizing the set of three-coupled Gross-Pitaevskii equations, the wave functions of the components are found. An analytical approximation for the surfactant thickness in the prewetting phase is presented. The results indicate that the surfactant thickness in the prewtting phase varies linearly with the chemical potential ratio in the logarithmic scale.
