Vapour-liquid phase transition and metastability [PDF]

ESAIM: Proceedings and Surveys, 2019
The paper deals with the modelling of the relaxation processes towards thermodynamic equilibrium in a liquid-vapour isothermal mixture. Focusing on the van der Waals equation of state, we construct a constrained optimization problem using Gibbs ...

Strain induced structural phase transition and compositional dependent magnetic phase transition in Ti doped Bi0.80Ba0.20FeO3 ceramics

Heliyon, 2022
Bi0.80Ba0.20Fe1-xTixO3 (0≤x≤0.10) samples are prepared using solid state reaction technique. Bi3+ site is replaced with 20 % Ba2+ which induced structural modification from rhombohedral to pseudo cubic accompanied by the creation of oxygen vacancies ...

Peccei-Quinn phase transition at LIGO

Journal of High Energy Physics, 2020
The LIGO observatories can potentially detect stochastic gravitational waves arising from phase transitions which happened in the early universe at temperatures around T ∼ 108 GeV.

Phase-Transition Microcavity Laser

, 2023
Liquid-crystal microcavity lasers have attracted considerable attention because of their extraordinary tunability and sensitive response to external stimuli, and because they operate generally within a specific phase.

Akimotoite to perovskite phase transition in MgSiO3 [PDF]

, 2004
The akimotoite to perovskite phase transition of MgSiO3 is shown by first principles calculations to have a negative Clapeyron slope, consistent with experimental observations.

QCD-induced electroweak phase transition

Journal of High Energy Physics, 2018
Phase transitions associated with nearly conformal dynamics are known to lead to significant supercooling. A notorious example is the phase transition in Randall-Sundrum models or their CFT duals.

Line Phase Transitions

Physical Review Letters, 1988
Les phenomenes d'adsorption en geometries non standard, et en particulier en mouillage de surfaces courbes, revelent des caracteristiques nouvelles et inattendues. Contrairement aux recentes previsions, les transitions de phase d'adsorption sur des substrats cylindriques peuvent continuer d'exister quand la longueur de correlation ξ de la taille d ...

A compressible mixture model with phase transition [PDF]

, 2013
We introduce a new thermodynamically consistent diffuse interface model of Allen--Cahn/Navier--Stokes type for multi-component flows with phase transitions and chemical reactions.
