Tunneling Dynamics of the Halves of a Double-Well Trap Containing a Bose-Einstein Condensate
Zhao-Xian Yu, Jiao Zhi-Yong
Abstract
In this paper, we have studied tunneling dynamics of the halves of a double-well trap containing a Bose–Einstein condensate. It is found that there exist step structure and macroscopic quantum self-trapping of population difference of atoms, and exist Shapiro-like steps of atomic tunneling current. Both the population difference and the atomic tunneling current depend strongly on the total number of atoms and the initial phase difference.
