Résumé :
Using the linear sigma model coupled with dynamical quarks, we investigate the effect of rotation on chiral restoration in strongly interacting matter by considering a rigidly rotating plasma in unbounded Minkowski space-time. At large distances from the rotation axis, the medium gets hotter and the sigma condensate melts, leading to the natural „firewall” boundary condition σ = 0 on the light cylinder, introduced in Ref. [1]. As a result, the system is either in a mixed phase, confined in the vicinity of the rotation axis and deconfined close to the light cylinder, or in a purely deconfined state. Our present study investigates the impact of quantum corrections, which become dominant close to the light cylinder [2], on the phase diagram of the system.
