dc.description.abstract | A theoretical model is presented which explains the dominant decoherence process
in a microcavity polariton condensate. The mechanism which is invoked is the effect of self-phase
modulation, whereby interactions transform polariton number fluctuations into random energy
variations. The model shows that the phase coherence decay, g
(1)( ), has a Kubo form, which can
be Gaussian or exponential, depending on whether the number fluctuations are slow or fast. This
fluctuation rate also determines the decay time of the intensity correlation function, g
(2)( ), so it
can be directly determined experimentally. The model explains recent experimental measurements
of a relatively fast Gaussian decay for g
(1)( ), but also predicts a regime, further above threshold,
where the decay is much slower. | en |
