Abstract

We have studied two-body correlations of atoms in an expanding cloud above and below the Bose-Einstein condensation threshold. The observed correlation function for a thermal cloud shows a bunching behavior, whereas the correlation is flat for a coherent sample. These quantum correlations are the atomic analog of the Hanbury Brown Twiss effect. We observed the effect in three dimensions and studied its dependence on cloud size.

After submission of this manuscript we became aware of a related experiment concerning atom correlations in an atom laser ( 26 ). We thank R. Sellem of the Détection Temps Position Image Technology Division (supported by the Mission Ressources et Compétences Technologiques–CNRS Federation FR2764 and by the Université Paris-Sud) for a decisive role in the development of the time-to-digital converter and O.
