Dynamics of false-vacuum bubbles [PDF]
The possibility of localized inflation is investigated by calculating the dynamics of a spherically symmetric region of false vacuum which is separated by a domain wall from an infinite region of true vacuum. For a range of initial conditions, the false-vacuum region will undergo inflation.

Collapse of Vacuum Bubbles in a Vacuum [PDF]
Motivated by the discovery of a plenitude of metastable vacua in a string landscape and the possibility of rapid tunneling between these vacua, we revisit the dynamics of a false vacuum bubble in a background de Sitter spacetime.

Cavitation And Bubble Dynamics [PDF]
Abstract The book describes and explains the fundamental physical processes involved in bubbly dynamics and the phenomenon of cavitation. The study of cavitation and bubbly flow applies to many areas of interest; from valve damage in hydroelectric equipment, ship propellors and internal combustion engines to the performance of ...

Master equation approach to DNA-breathing in heteropolymer DNA
After crossing an initial barrier to break the first base-pair (bp) in double-stranded DNA, the disruption of further bps is characterized by free energies between less than one to a few kT. This causes the opening of intermittent single-stranded bubbles.

Scaling laws for jets of single cavitation bubbles [PDF]
Fast liquid jets, called micro-jets, are produced within cavitation bubbles experiencing an aspherical collapse. Here we review micro-jets of different origins, scales and appearances, and propose a unified framework to describe their dynamics by using ...

Inertia and chiral edge modes of a skyrmion magnetic bubble
The dynamics of a vortex in a thin-film ferromagnet resembles the motion of a charged massless particle in a uniform magnetic field. Similar dynamics is expected for other magnetic textures with a nonzero skyrmion number.

Shock Wave Development in the Collapse of a Cloud of Bubbles [PDF]
A numerical simulation of the collapse of a cloud of bubbles has been used to demonstrate the development of an inwardly propagating shock wave which grows rapidly in magnitude.

Influence of the accommodation coefficient on nonlinear bubble oscillations [PDF]
This paper numerically investigates the effect of mass transfer processes on spherical single bubble dynamics using the Hertz–Langmuir–Knudsen approximation for the mass flux across the interface.

Numerical analysis of bubble growth in a molten steel/(N2,H2) supersaturation system
A water/carbon dioxide system was used to study bubble growth dynamics in a molten steel/(N2,H2) supersaturation system. Bubble nucleation and growth mechanism models in the aqueous solution and the molten steel were respectively established.Bubble ...
