Characterizing atom sources with quantum coherence
Researchers can characterize atom sources by coherence properties, viewed either in the wave or particle picture, in analogy with quantum optics. First-order coherence measures amplitude fluctuations related to, for example, fringe visibility in an interferometer. Second-order coherence measures intensity variations as manifested in laser light speckle.
