In this Letter we propose a fundamental test for probing the thermal nature of the spectrum emitted by sonoluminescence. We show that two-photon correlations can in principle discriminate between real thermal light and the pseudo-thermal squeezed-state photons typical of models based on the dynamic Casimir effect, Two-photon correlations provide a powerful experimental test for various classes of sonoluminescence models.

Abstract
In this Letter we propose a fundamental test for probing the thermal nature of the spectrum emitted by sonoluminescence. We show that two-photon correlations can in principle discriminate between real thermal light and the pseudo-thermal squeezed-state photons typical of models based on the dynamic Casimir effect, Two-photon correlations provide a powerful experimental test for various classes of sonoluminescence models.File in questo prodotto:
