DYNAMICAL VISCOSITY OF NUCLEATING BUBBLES

Dynamical viscosity of nucleating bubbles

We study the viscosity corrections to the growth rate of nucleating bubbles in a slightly supercooled first order phase transition in 1 + 1 and 3 + 1 dimensional scalar field theory. We propose a microscopic approach that leads to the non-equilibrium equation of motion of the coordinate that describes small departures from the critical bubble and allows to extract the growth rate consistently i...

Viscosity destabilizes sonoluminescing bubbles.

In single-bubble sonoluminescence (SBSL) microbubbles are trapped in a standing sound wave, typically in water or water-glycerol mixtures. However, in viscous liquids such as glycol, methylformamide, or sulphuric acid it is not possible to trap the bubble in a stable position. This is very peculiar as larger viscosity normally stabilizes the dynamics. Suslick and co-workers call this new myster...

Tunneling and propagation of vacuum bubbles on dynamical backgrounds

In the context of bubble universes produced by a first-order phase transition with large nucleation rates compared to the inverse dynamical time scale of the parent bubble, we extend the usual analysis to non-vacuum backgrounds. In particular, we provide semi-analytic and numerical results for the modified nucleation rate in FLRW backgrounds, as well as a parameter study of bubble walls propaga...
