To understand sQGP through non-topological FL model

TL;DR

This paper investigates the non-topological FL model at finite temperature and density, analyzing soliton solutions across deconfinement, revealing their different physical interpretations before and after the phase transition, and providing a phase diagram.

Contribution

It offers a detailed analysis of soliton solutions in the non-topological FL model during deconfinement, clarifying their physical meanings and phase structure.

Findings

Solitons before deconfinement represent hadrons.

Solitons after deconfinement represent quark bound states.

A phase diagram of the model is provided.

Abstract

The non-topological FL model is studied at finite temperature and density. The soliton solutions of the FL model in deconfinement phase transition are solved and thoroughly discussed for different boundary conditions. We indicate that the solitons before and after the deconfinement have different physical meanings: the soliton before deconfinement represents hadron, while the soliton after the deconfinement represents the bound state of quarks which leads to a sQGP phase. The corresponding phase diagram is given.
