Chiral restoration phase transition within the quarkyonic matter

TL;DR

This paper explores a mechanism for confining yet chirally symmetric matter at low temperatures and high densities, demonstrating that a diffused quark Fermi surface does not eliminate this phase.

Contribution

It introduces a model with a diffused quark Fermi surface to show the persistence of confining but chirally symmetric matter under these conditions.

Findings

Diffused quark Fermi surface does not destroy confining chirally symmetric matter.

Proposes a new mechanism for phase transition in quarkyonic matter.

Supports the existence of a confining but chirally symmetric phase at low temperatures.

Abstract

We overview a possible mechanism for confining but chirally symmetric matter at low temperatures and large densities. As a new development we employ a diffused quark Fermi surface and show that such diffusion does not destroy possible existence of a confining but chirally symmetric matter at low temperatures and large density.
