Perturbative thermodynamics at nonzero isospin density for cold QCD

TL;DR

This paper employs next-to-leading-order perturbation theory to analyze how finite isospin density influences the thermodynamics of cold QCD matter, incorporating quark masses and comparing with lattice results.

Contribution

It provides a perturbative calculation of cold QCD thermodynamics at nonzero isospin density including quark masses, validated against lattice data.

Findings

Perturbative results agree with lattice data at certain densities.

Finite isospin density significantly affects thermodynamic properties.

Quark mass effects are incorporated into the perturbative framework.

Abstract

We use next-to-leading-order in perturbation theory to investigate the effects of a finite isospin density on the thermodynamics of cold strongly interacting matter. Our results include nonzero quark masses and are compared to lattice data.
