Bubble 36Ar and its new breathing modes

Physics Letters B
The bubble nuclei are important components of exotic nuclear structures characterized by special depletions of central densities. Focusing on bubble structures of 36Ar, the characterizations of bubble nuclei were explored with the framework of the ...

Bubble dynamics in drinks

EPJ Web of Conferences, 2014
This study introduces two physical effects known from beverages: the effect of sinking bubbles and the hot chocolate sound effect. The paper presents two simple „kitchen” experiments.

Dynamics of a single cavitation bubble near an oscillating boundary

Scientific Reports
Cavitation and its effects are well investigated, especially single bubble cavitation and its collapse near rigid and elastic boundaries. In our current article, we investigated novel experiments of a single cavitation bubble near an oscillatory boundary.

Quantum tunnelings with global charge

, 1994
We investigate quantum tunneling in the theory of a complex scalar field with a global $U(1)$ symmetry when the charge density of the initial configuration does not vanish.

Bubble coalescence in breathing DNA: Two vicious walkers in opposite potentials

, 2006
We investigate the coalescence of two DNA-bubbles initially located at weak segments and separated by a more stable barrier region in a designed construct of double-stranded DNA.

Dynamics of gas bubble growth in a supersaturated solution with Sievert's solubility law

, 2009
This paper presents a theoretical description of diffusion growth of a gas bubble after its nucleation in supersaturated liquid solution. We study systems where gas molecules completely dissociate in the solvent into two parts, thus making Sievert's ...

Gas bubble dynamics

Reviews of Modern Physics
The study of gas bubble dynamics in liquids is justified by the numerous applications and natural phenomena where this two-phase flow is encountered. Gas bubbles move as forces are applied to them; their dynamics are full of nuances that need to be addressed carefully.

Bubble dynamics in DNA

, 2003
The formation of local denaturation zones (bubbles) in double-stranded DNA is an important example for conformational changes of biological macromolecules. We study the dynamics of bubble formation in terms of a Fokker-Planck equation for the probability

Theoretical study on the movements of bubbles

Ultrasonics Sonochemistry
The radial and translational motions of multiple interacting spherical bubbles are obtained using classical Newton mechanics. It is seen that bubbles not only move in straight line, but also in circular motion.

Spherical Solutions of an Underwater Explosion Bubble

Shock and Vibration, 1998
The evolution of the 1D explosion bubble flow field out to the first bubble minimum is examined in detail using four different models. The most detailed is based on the Euler equations and accounts for the internal bubble fluid motion, while the simplest
