Effective Two-State Model and NOON States for Double-Well Bose-Einstein Condensates in Strong-Interaction Regime

摘要

The model of double-well Bose-Einstein condensates in the strong-interaction regime is shown to reduceadiabatically to an effective two-state model describing the Rabi oscillations between the two atomic Fock states |N,0〉and |0,N〉,and the NOON states of arbitrary ultracold atoms can therefore be generated periodically from the initialstate of either one of the Fock states.
