摘要：
本文研究了非相互作用气体在偏心凹坑势简谐势阱中的玻色-爱因斯坦凝聚。我们特别考虑的情况下，一个紧和深的酒窝潜力，这是由一个点的相互作用建模。这种点相互作用由狄拉克δ函数表示。通过数值计算，分析了原子密度、化学势、临界温度和冷凝分数、相对深度的作用以及韧窝势的位置。
英文摘要：
We investigate Bose-Einstein condensation of noninteracting gases in a harmonic trap with an off-center dimple potential. We specifically consider the case of a tight and deep dimple potential which is modelled by a point interaction. This point interaction is represented by a Dirac delta function. The atomic density, chemical potential, critical temperature and condensate fraction, the role of the relative depth and the position of the dimple potential are analyzed by performing numerical calculations.
