Thermodynamics of Deconfined Matter at Finite Chemical Potential in a Quasiparticle Description

TL;DR

This paper extends a quasiparticle model of deconfined matter's thermodynamics to finite chemical potential, aligning with lattice data and perturbative limits, and explores implications for dense matter in compact stars.

Contribution

It generalizes an effective quasiparticle model to include finite chemical potential, bridging lattice data and perturbative theory for deconfined matter.

Findings

Extended lattice equation of state to finite baryon density

Analyzed implications for cold, charge-neutral matter in stars

Provided a consistent thermodynamic framework at finite chemical potential

Abstract

An effective quasiparticle description of the thermodynamics of deconfined matter, compatible with both finite-temperature lattice data and the perturbative limit, is generalized to finite chemical potential. Within this approach, the available 4-flavor lattice equation of state is extended to finite baryon density, and implications for cold, charge-neutral deconfined matter in beta-equilibrium in compact stars are considered.
