Abstract

Using single atom detection offered by metastable helium atoms (He*), we are able to measure correlations between atoms. With this we have demonstrated second-order coherence of matter waves that emerge from amplified four-wave mixing (FWM). Our results provide the first second-order, or quantum test of coherence for amplified matter waves. Using the same detection scheme, we have investigated the onset of coherence during the formation of a Bose-Einstein condensate (BEC), attempting to reveal how the long-range order of a BEC is established. Our initial results support the existence of quasi-condensates.
