Atomic Coherence Effect on the Formation of Molecules via Photoassociation
原子相干对光缔合形成分子的影响

The influence of atomic coherence on the formation of a ultracold molecule from ultracold two-state atoms is discussed via photoassociation.By using the method of quantum statistics,it is found that under the action of atomic coherence,the molecular number vibrates with an approximate period and with reduced amplitude.Atomic coherence has a strong influence on the temporary of the whole photoassociation process,but the molecules are always subject to sub-Poisson statistical distribution.
