Phase Structure and Transport Properties of Dense Quark Matter

TL;DR

This paper reviews the phase structure of dense quark matter, focusing on how the high-density CFL phase evolves at lower densities, and discusses quasi-particle excitations and transport properties of dense QCD matter.

Contribution

It provides a comprehensive summary of the current understanding of dense quark matter phases and their transport properties, highlighting modifications from the CFL phase at lower densities.

Findings

CFL phase is the ground state at asymptotically high density

Transport properties of dense QCD matter are characterized

Modifications of the CFL phase at lower densities are discussed

Abstract

We provide a summary of our current knowledge of the phase structure of very dense quark matter. We concentrate on the question how the ground state at asymptotically high density -- color-flavor-locked (CFL) matter -- is modified as the density is lowered. We discuss the nature of the quasi-particle excitations, and present work on the transport properties of dense QCD matter.
