摘要：
We discuss coherent oscillations between two coupled quantum states of a Bose Einstein condensate in two-dimensional space at zero temperature. In the system we consider, weak interparticle repulsive interactions occur between the particles in state one only, while the state two particles remain non-interacting. Our theoretical analysis of the coupled generalized Gross Pitaevskii equations reveals various regimes of oscillatory dynamics for the relative phase and population imbalance between the two subsystems of the condensate, with the energy detuning between the two states being the controlling parameter of the system.
