温度相关类属阱中弱相互作用的玻色-爱因斯坦凝聚体

Weakly interacting Bose-Einstein condensates in temperature-dependent generic traps

E. Castellanos, F. Briscese, M. Grether, M. de Llano

摘要:

本文研究了在温度依赖的三维类属势场中的玻色-爱因斯坦凝聚体中,相互作用引起的凝聚温度的变化,直到s波散射长度的二阶.没有假设以外的平均场的方法和半经典近似,它表明,包括一个温度相关的陷阱,提高了经验值的数值参数相比,在以前的报告中获得的温度漂移。

英文摘要:

The shift in condensation temperature caused by interactions is studied up to second order in the s-wave scattering length in a Bose-Einstein condensate trapped in a temperature-dependent three-dimensional generic potential. With no assumptions other than the mean-field approach and semiclassical approximations it is shown that the inclusion of a temperature-dependent trap improves the empirical values of the numerical parameters compared to those obtained in previous reports on the temperature shift.
