Sonoluminescence is explained in terms of quantum radiation by moving interfaces between media of different polarizability. In a stationary dielectric the zero-point fluctuations of the electromagnetic field excite virtual two-photon states, which become real under perturbation due to motion of the dielectric. The sonoluminescent bubble is modeled as an optically empty cavity in a homogeneous dielectric. The problem of the photon emission by a cavity of time-dependent radius is handled in a… Expand
Sonoluminescence as a QED vacuum effect. I. The physical scenario
Several years ago Schwinger proposed a physical mechanism for sonoluminescence in terms of changes in the properties of the quantum-electrodynamic vacuum state during collapse of the bubble. ThisExpand
Quantum radiation from a moving dielectric semi-infinite half-space is investigated in a scalar model in two, three, and arbitrary integer spatial dimensions. The dielectric medium is non-dispersiveExpand
Sonoluminescence and the QED vacuum
In this talk I shall describe an extension of the quantum-vacuum approach to sonoluminescence proposed several years ago by J.Schwinger. We shall first consider a model calculation based on BogolubovExpand
Sonoluminescence as a QED vacuum effect: probing Schwinger's proposal
Several years ago Schwinger proposed a physical mechanism for sonoluminescence in terms of photon production due to changes in the properties of the quantum-electrodynamic (QED) vacuum arising from aExpand
Sonoluminescence as a QED vacuum effect. II. Finite volume effects
In a companion paper [quant-ph/9904013] we have investigated several variations of Schwinger's proposed mechanism for sonoluminescence. We demonstrated that any realistic version of Schwinger'sExpand
Single-bubble sonoluminescence as Dicke superradiance at finite temperature
Sonoluminescence is a process in which a strong sound field is used to produce light in liquids. We explain sonoluminescence as a phase transition from ordinary fluorescence to a superradiant phase.Expand
New suggestion concerning the origin of sonoluminescence
Abstract We suggest a new mechanism where sonoluminescence is produced by the tremendously large adiabatic pressure pulse (shock wave) generated by the close to supersonic (or above) impact of theExpand
Vacuum fluctuations and moving atoms/detectors: From Casimir-Polder to Unruh effect
In this note we review some recent results on corrections to the Casimir?Polder retardation force due to atomic motion and present a preliminary critique on one recently proposed cavity QED schemeExpand
Collision-induced emission at high temperatures and densities: modeling of the sonoluminescence spectra
It is well known that infrared inactive gases, such as nitrogen and hydrogen, absorb infrared radiation if the gas densities are sufficiently high. The absorption is of a supramolecular nature,Expand
Oscillator-field model of moving mirrors in quantum optomechanics
We present a microphysics model for the kinematics and dynamics of optomechanics describing the coupling between an optical field, modeled here by a massless scalar field, and the internal andExpand


Scattering theory of waves and particles
Much progress has been made in scattering theory since the publication of the first edition of this book fifteen years ago, and it is time to update it. Needless to say, it was impossible toExpand
Quantum Fields in Curved Space
This book presents a comprehensive review of the subject of gravitational effects in quantum field theory. Although the treatment is general, special emphasis is given to the Hawking black holeExpand
Advanced field theory : micro, macro, and thermal physics
This work begins by distinguishing the difference between quantum mechanics and quantum field theory. It then attempts to extend field theory by adding a thermal degree of freedom to phenomenaExpand
