Detecting correlations in condensates
Résumé
In our laboratory, we have been developing measurement methods to extract at two-particle correlations functions in degenerate gases. Simple examples include the observation of correlated atom pairs in a four wave mixing geometry, and Hanbury Brown-Twiss type interferometry. In these experiments we observe the correlations in momentum space. We have also been able to observe density fluctuations in position space by using in situ imaging on an atom chip. I will attempt to review some of the possibilities open to us and discuss some of our plans for the immediate future.
