Quantum Dynamics of Two-component Bose-Einstain Condensate with a Coupling Drive
摘要
Abstract
In this paper, the time evolution of the atomicity density of two-component Bose-einstein condensates (BEC) is studied and it is demonstrated that the evolution of condensate density in long time, which presents a typical quantum collapse and revival in a complex way, is rather different from that in short time. Furthermore,quantum collapse of the system and revival characteristic will not change within a fairly wide range of parameters. The influence of the Rabi frequency, the strength of the coupling drive and the initial value of the relative phase on the evolution properties of atomicity density are also discussed.关键词
