摘要

We examine in terms of exact solutions of the time-dependent Schrödinger 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 (â_L⁺â_L - â_R ⁺â_R) of species A between the two wells is studied analytically.
