| 英文摘要 | We examine in terms of exact solutions of the time-dependent schrodinger equation, the quantum tunnelling process in bose-einstein condensates of two interacting species trapped in a double well configuration. based on the two series of time-dependent su(2) gauge transformations, we diagonalize the hamilton operator and obtain analytic time-evolution formulas of the population imbalance and the berry phase. the particle population imbalance (a(l)(+)al - a(r)(+)a(r)) of species a between the two wells is studied analytically. |
