Abstract:

  We study the rotation effects of the hot and dense OCD matter in a nonperturbative regime by the gauge/gravity duality. We use the gravitational model thatis designated to match the state-of-the-art lattice data on the thermal properties oi(2+1)-flavor OCD and predict the location of the critical endpoint and the first-ordeiphase transition line at large baryon chemical potential without rotation. Afteiintroducing the angular velocity via a local Lorentz boost,we investigate thethermodynamic quantities for the system under rotation in a self-consistent way. Wfind that the critical temperature and baryon chemical potentidl associated with theOCD phase transition decrease as the angular velocity increases. Moreover, someinteresting phenomena are observed near the critical endpoint. We then construct the3-dimensional phase diagram of the OCD matter in terms of temperature, baryonchemical potential, and angular velocity. As a parallel investigation, we also considetthe gravitational model of $SU(3)$ pure gluon system, for which the 2-dimensiondphase diagram associated with temperature and angular velocity has been predictedThe corresponding thermodynamic quantities with rotation are investigated.
