Resolving the space-time structure of sonoluminescence by intensity interferometry

We analyze the spatial and temporal resolving power of two-photon intensity interferometry for the light emitting source in single bubble sonoluminescence (SBSL). We show that bubble sizes between several 10 nm and 3 um can be resolved by measuring the transverse correlation function, but that a direct determination of the flash duration via the longitudinal correlation function works only for SBSL pulses which are shorter than 0.1 ps. Larger pulse lengths can be determined indirectly from the intercept of the angular correlator at equal photon frequencies. The dynamics of the bubble is not accessible by two-photon interferometry.

Photon Spin and the Shape of the Two-Photon Correlation Function

We use the covariant current formalism to derive the general form of the 2-photon correlation function for fully chaotic sources. Motivated by the recent discussion in the literature we concentrate on the effects from the photon spin on the correlator. We show that for locally thermalized expanding sources, like those expected to be created in relativistic heavy ion collisions, the only change relative to 2-pion interferometry is a statistical factor 1/2 for the overall strength of the correlation which results from the experimental averaging over the photon spin.
