Investigating Casimir effect in sonoluminescence bubble: A brief overview

Abstract

The focus of our investigation is the feasibility of examining the Casimir effect in a spherically symmetric sonoluminescence bubble. Our recommendations are based on an in-depth analysis of the relevant literature and experimental data. To forecast the expansion time of the bubble under irradiated shock waves, we primarily relied on Schwinger calculations. Furthermore, we addressed the inconsistencies associated with the failure to link sonoluminescence (SL) with the Casimir effect. Our findings indicate that SL is a highly delicate and reliant metric, with its measurement relying on variables such as the type of gas used to produce the bubble, fluid and gas temperatures, surface tension, density, pressure, and radius. Based on our analysis, we conclude by proposing adjustments to various gases, particularly at different temperatures, to accurately assess SL using Casimir forces and energy. We believe that our study will aid in the acceleration of future investigations into precisely measuring SL bubbles.
