First, we study the rotation effects of the hot and dense QCD matter in a non-perturbative regime by the gauge/gravity duality. We use the gravitational model that is designated to match the state-of-the-art lattice data on the thermal properties of (2+1)-flavor QCD and predict the location of the critical endpoint and the first-order phase transition line at large baryon chemical potential without rotation. After introducing the angular velocity via a local Lorentz boost, we investigate the thermodynamic quantities for the system under rotation in a self-consistent way. We find that the critical temperature and baryon chemical potential associated with the QCD phase transition decrease as the angular velocity increases. Moreover, some interesting phenomena are observed near the critical endpoint.

Secondly we calculate the spectral function and dissociation of the heavy vector mesons with the presence of an intense magnetic field in a hot and dense medium. The energy loss of heavy quark in a Magnetized thermal dense QCD matter is also studied. We find that the drag force of heavy quark and jet quenching parameter behave an enhancement near the phase transition temperature. The peak values of drag force and jet quenching parameter are pushed towards lower temperature with increasing B or μ. The heavy quark may lose more energy when perpendicular to magnetic field which is consistent with the results of jet quenching parameter.
