Non-equilibrium cumulants within model A from crossover to first-order phase transition side

نویسندگان

چکیده

We study the non-equilibrium cumulants of chiral order parameter field ({\sigma} field) in different phase transition scenarios via Langevin dynamics. Cumulants up to fourth-order have been calculated based on spacetimedependent {\sigma} configurations from event-by-event numerical simulations. By limiting cooling system a Hubble-like way, out-of-equilibrium illustrate clear memory effects during evolution. Both signs and magnitudes high-order differ equilibrium ones below temperature. Especially, dynamical grow more intensively first-order side than they do crossover side. In addition, analysis offequilibrium hypothetical freeze-out lines present non-monotonic curves large chemical potential region.

Primordial Black Holes from Non–equilibrium Second Order Phase Transition

The collapse of sufficiently large closed domain wall produced during second order phase transition in the vacuum state of a scalar field can lead to the formation of black hole. The origin of domain walls with appropriate size and energy density could be a result of evolution of an effectively massless scalar field at the inflational epoch. We demonstrate that in this case the situation is val...

Simple model of first-order phase transition

One-dimensional model of a system where first-order phase transition occurs is examined in the present paper. It is shown that basic properties of the phenomenon, such as a well defined temperature of transition, are caused both by existence of a border between the phases and the fact that only in the vicinity of that border it is possible for molecules to change their phase. Not only the model...

First order phase transition in a model of quasicrystals

We introduce a family of two-dimensional lattice models of quasicrystals, using a range of square hard cores together with a soft interaction based on an aperiodic tiling set. Along a low temperature isotherm we find, by Monte Carlo simulation, a first order phase transition between disordered and quasicrystalline phases. PACS numbers: 61.44.Br, 64.60.De (Some figures in this article are in col...

First Order Phase Transition in a Model for Generalised Statistics

A first order phase transition is found in a model which was introduced originally by Murthy and Shankar [Phys. Rev. B 60, 6517 (1999)] to describe systems of generalised exclusion statistics. I characterise the phase transition in the canonical and grandcanonical ensebles for the case when the statistical exclusion parameter is 1, which corresponds to the Fermi exclusion statistics. We observe...

A strictly hyperbolic equilibrium phase transition model

This Note is concerned with the strict hyperbolicity of the compressible Euler equations equipped with an equation of state that describes the thermodynamical equilibrium between the liquid phase and the vapor phase of a fluid. The proof is valid for a very wide class of fluids. The argument only relies on smoothness assumptions and on the classical thermodynamical stability assumptions, that r...
