    "abstract": "We extend Schwinger\u0027s ideas regarding sonoluminescence by explicitly\ncalculating the Bogolubov coefficients relating the QED vacuum states\nassociated with changes in a dielectric bubble. Sudden (non-adiabatic) changes\nin the refractive index lead to an efficient production of real photons with a\nbroadband spectrum, and a high-frequency cutoff that arises from the asymptotic\nbehaviour of the dielectric constant.",
