Equation of State and Phase Fluctuations near the Chiral Critical Point

TL;DR

This paper investigates the thermodynamics, critical behavior, and phase fluctuations of dense matter near the chiral critical point, integrating lattice QCD results with nuclear matter properties to understand phase separation effects.

Contribution

It presents a parameterized equation of state that unifies lattice QCD data at zero chemical potential with nuclear matter properties at zero temperature.

Findings

Finite size effects can diminish phase separation near the critical point.

The equation of state accurately matches lattice QCD and nuclear matter data.

Critical exponents and amplitudes are characterized near the chiral critical point.

Abstract

The thermodynamics and critical exponents and amplitudes of high temperature and dense matter near the chiral critical point are studied. The parameterized equation of state matches on to that calculated with lattice QCD at zero chemical potential and to the known properties of nuclear matter at zero temperature. The extent to which finite size effects wash out the phase separation near the critical point is determined.
