费什巴赫共振中的双稳态

Bistability in Feshbach Resonance

Hong Y. Ling

摘要:

利用一种具有种内费什巴赫共振的原子-分子耦合凝聚体,研究了单向光学环形腔存在和不存在时的物质波双稳态.特别是,一组条件的推导,允许双稳态的阈值,由于两个身体的s波散射和腔介导的两个身体的相互作用,要确定分析。后者的双稳态被发现支持,不仅在混合(原子-分子)状态和纯分子状态之间的转换,在前双稳态,但也两个不同的混合状态之间的转换。

英文摘要:

A coupled atom-molecule condensate with an intraspecies Feshbach resonance is employed to explore matter wave bistability both in the presence and in the absence of a unidirectional optical ring cavity. In particular, a set of conditions are derived that allow the threshold for bistability, due both to two-body s-wave scatterings and to cavity-mediated two-body interactions, to be determined analytically. The latter bistability is found to support, not only transitions between a mixed (atom-molecule) state and a pure molecular state as in the former bistability, but also transitions between two distinct mixed states.
