研究了玻色-爱因斯坦凝聚体(BEC)在高斯势垒谐振子陷阱中的隧道效应。在一定条件下，初始凝析油在隧穿时间后演化为两个单独运动的凝析油。作为比较，给出了两个运动凝聚体之间的干涉图样，并进一步证明了整体相的存在。
The tunneling effect of Bose—Einstein condensate (BEC) in a harmonic trap with a Gaussian energy barrier is studied in this paper. The initial condensate evolves into two separate moving condensates after the tunneling time under certain conditions. The interference pattern between the two moving condensates is given as a comparison and as a further demonstration of the existence of the global phase.
