A quarksonic matter at high isospin density

TL;DR

This paper proposes and explores a new phase called quarksonic matter at high isospin density, where quark and mesonic excitations coexist, using theoretical models and limits to analyze its properties.

Contribution

It introduces the concept of quarksonic matter at high isospin density and analyzes its phase diagram and thermodynamics in large N_c and asymptotically free limits.

Findings

Sketches phase diagram for quarksonic matter in large N_c limit

Studies pion superfluidity in quarksonic matter using perturbative and effective models

Provides insights into thermodynamics of quarksonic matter at high isospin density

Abstract

Analogous to the quarkyonic matter at high baryon density in which the quark Fermi seas and the baryonic excitations coexist, it is argued that a "quarksonic matter" phase appears at high isospin density where the quark (antiquark) Fermi seas and the mesonic excitations coexist. We explore this phase in detail in both large $N_c$ and asymptotically free limits: In large $N_c$ limit, we sketch a phase diagram for the quarksonic matter. In the asymptotically free limit, we study the pion superfluidity and thermodynamics of the quarksonic matter by using both perturbative calculations and effective model.
