The Splitting of Chiral and Deconfinement Phase Transitions induced by Rotation

TL;DR

This paper investigates how rotation affects chiral and deconfinement phase transitions in QCD, revealing that rotation can split these transitions and induce a phase that is chiral symmetric but confined.

Contribution

It demonstrates, using the PNJL model, that rotation can differentially influence chiral and deconfinement transitions, leading to a novel phase where chiral symmetry is restored but confinement persists.

Findings

Rotation catalyzes the chiral phase transition.

Rotation decelerates the deconfinement phase transition.

A chiral symmetric but confined phase is induced by rotation.

Abstract

The chiral and deconfinement phase transitions under rotation have been simultaneously investigated in the Polyakov-Nambu-Jona-Lasinio (PNJL) model. An interesting observation has been found that the chiral phase transition is catalyzed and the deconfinement phase transition is decelerated by rotation, therefore a chiral symmetric but confined phase is induced by rotation, which indicates that chiral dynamics and gluon dynamics can be split by rotation.
