Bose–Einstein correlations and sonoluminescence

Sonoluminescence may be studied in detail by intensity correlations among the emitted photons. As an example, an experiment to measure the size of the light‐emitting region by the Hanbury Brown–Twiss effect is discussed. It is shown that single bubble sonoluminescence is almost ideally suited for study by this method and that plausible values for the physical parameters are within easy experimental reach. A sequence of two‐ and higher‐order photon correlation experiments is outlined.
