摘要:

我们提出了一种方法来产生一定数量的基态原子的绝热减少的深度的势阱,限制了一个退化的玻色气体与排斥相互作用。使用各种方法,我们绘制出的最大数量的粒子,可以支持的以及作为一个函数的井深和相互作用强度,涵盖了唐克斯气体的极限情况下,以及平均场制度。我们还估计了绝热性的时间尺度,并讨论了最近观察到的原子序数压缩(Chuu等人,物理修订信函{ \bf 95},260403(2005))。

英文摘要:

We propose a method to produce a definite number of ground-state atoms by adiabatic reduction of the depth of a potential well that confines a degenerate Bose gas with repulsive interactions. Using a variety of methods, we map out the maximum number of particles that can be supported by the well as a function of the well depth and interaction strength, covering the limiting case of a Tonks gas as well as the mean-field regime. We also estimate the time scales for adiabaticity and discuss the recent observation of atomic number squeezing (Chuu et al., Phys. Rev. Lett. {\bf 95}, 260403 (2005)).
