dc.description.abstract | The fundamental mechanisms which control the phase coherence of the polariton Bose-Einstein
condensate (BEC) are determined. It is shown that the combination of number fluctuations and
interactions leads to decoherence with a characteristic Gaussian decay of the first-order correlation
function. This line shape, and the long decay times ( 150 ps) of both first- and second-order correlation
functions, are explained quantitatively by a quantum-optical model which takes into account interactions,
fluctuations, and gain and loss in the system. Interaction limited coherence times of this type have been
predicted for atomic BECs, but are yet to be observed experimentally. | en |
