The standard vacuum bounce formalism suffers from inconsistencies when applied to thermal bubble nucleation, for which ad hoc workarounds are commonly adopted. Identifying the length scales on nucleation takes place, we demonstrate how construction of an effective description these naturally resolves problems formalism. Further, by utilising high-temperature dimensional reduction, make a connec...

Cold atomic gases offer the prospect of simulating physics very early universe in laboratory. In condensate phase, gas is described by a field theory with key features high energy particle theory. This paper describes three level system which undergoes first order phase transition through nucleation bubbles. The theoretical investigation shows bubbles nucleating two dimensions at non-zero tempe...

In this work we present experiments and simulations on the nucleation successive dynamics of laser-induced bubbles inside liquid droplets in free-fall motion, i.e. a case where are subjected to influence free boundary all directions. Within spherical millimetric droplet, have investigated secondary induced by rarefaction wave that is produced when shock emitted plasma reflects at drop surface. ...

We study the process of black brane evaporation through emission D-branes. Gravitational solutions describing branes in asymptotically anti-de Sitter spacetimes, which are holographically dual to field theory states at finite temperature and density, have previously been found exhibit an instability due nucleation. Working setting D3-branes on conifold, we construct static Euclidean this nuclea...

Nucleation is the formation of a new phase that has ability to irreversibly and spontaneously grow into large-sized nucleus within body metastable parent phase. In this experimental work, effect wettability on incipiation vacuum-driven bubble nucleation, boiling, consequent rate evaporative cooling are studied. One hydrophilic (untreated), three hydrophobic (chlorinated polydimethylsiloxane, ch...

We consider the nucleation process associated with capillary condensation of a vapor in a hydrophobic cylindrical pore (capillary evaporation). The liquid-vapor transition is described within the framework of a simple lattice model. The phase properties are characterized both at the mean-field level and with Monte Carlo simulations. The nucleation process for the liquid to vapor transition is t...

The bubble nucleation temperatures of several organic liquids (methanol, ethanol, butanol, n-heptane) on stress-minimized platinum (Pt) films supported by SiN membranes is examined by pulse-heating the membranes for times ranging from 1 µs to 10 µs. The results show that the nucleation temperatures increase as the heating rates of the Pt films increase. Measured nucleation temperatures approach...

We report an experimental study of bubble dynamics in a non-Newtonian fluid subjected to a pressure decrease. The fluid is a hydrogel, composed of water and a synthetic clay, prepared and sandwiched between two glass plates in a Hele-Shaw geometry. The rheological properties of the material can be tuned by the clay concentration. As the imposed pressure decreases, the gas initially dissolved in...
