摘要:
We investigate the magnetized QCD matter and chiral phase transition in a (2 +1)-flavor Nambu–Jona- Lasinio (NJL) model at finite temperature and chemical potential by comparing the contributions from the tensor spin polarization (TSP) and anomalous magnetic moment (AMM) of quarks. On the other hand, 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 quarkyonic phase is induced by rotation, which indicates that chiral dynamics and gluon dynamics can be splitted by rotation.
