| 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. |
