Sonoluminescence as a Cooperative Many Body Phenomenon
نویسندگان
چکیده
We propose that sonoluminescence occurs due to the cooperative interaction of the matter in the bubble with a radiation field. We illustrate how the collective spontaneous emission of population inverted atomic or molecular states can lead to a time scale of the light pulse which is consistent with that observed in experiments. Pumping by an ultrasound source provides the necessary condition for the inverted states to be correlated over a small volume to trigger sonoluminescence. Experimentally observed role of trace impurities is seen to be consistent in this picture. [S0031-9007(97)04952-1]

Direct observations of single sonoluminescence pulses
Previous reports have described experimental measurements and theoretical descriptions of sonoluminescence without clearly resolving the physical events that underlie this phenomenon. Although incomplete, these results have led to suggestions that sonoluminescence might be such an extreme process that it could serve as an unusual inertial confinement source of fusion neutrons. Such a possibilit...
متن کاملSonoluminescence from Nonaqueous Liquids: Emission from Small Molecules
Sonoluminescence spectra from nonaqueous liquids under a variety of gases are presented. Ultrasonic irradiation of alkanes under Ar leads to emission from C2, C2H, and CH. When nitrogen is present, emission is seen from CN. When oxygen is present, emission from COz, CH, and OH is observed. Ultrasonic irradiation of tetrachloroethylene or CCI4 leads to emission from CI2. The intensity of sonolum...

In the nal few years of his life, Julian Schwinger proposed that the \dynamical Casimir e ect" might provide the driving force behind the puzzling phenomenon of sonoluminescence. Motivated by that exciting suggestion, I have computed the static Casimir energy of a spherical cavity in an otherwise uniform material with dielectric constant and permeability . As expected the result is divergent; y...
متن کاملSonoluminescence : how bubbles glow DOMINIK HAMMER and LOTHAR FROMMHOLD
We review recent attempts to elucidate the phenomenon of sonoluminescence in terms of fundamental principles. We focus mainly on the processes which generate the light, but other relevant facts, such as the bubble dynamics, must also be considered for the understanding of the physics involved. Our emphasis is on single bubble sonoluminescence which in recent years has received much attention, b...

In the final few years of his life, Julian Schwinger proposed that the “dynamical Casimir effect” might provide the driving force behind the puzzling phenomenon of sonoluminescence. Motivated by that exciting suggestion, we have computed the static Casimir energy of a spherical cavity in an otherwise uniform material. As expected the result is divergent; yet a plausible finite answer is extract...
