Description
It is well established from the first principle lattice QCD calculations that, at low baryon chemical potential, the transition from the confined hadronic phase to the deconfined partonic phase is not a simple first or second-order phase transition but rather a smooth crossover. The crossover is characterized by rapid and continuous changes in thermodynamic observables, such as the pressure, energy density, entropy density, and susceptibilities of the conserved quantities such as baryon number, electric charge and strangeness. Recently, rapid rotation and strong magnetic-field have emerged as important phenomena in heavy-ion physics as many experimental and theoretical developments have highlighted the importance of effects of rotation and magnetic field on strongly interacting matter.
In the present work, a thermodynamically consistent hybrid equation of state (EOS) is developed which describes the smooth interpolation between confined hadronic and deconfined QGP phase across crossover under the effects of rotation and magnetic-field at finite chemical potential. The temperature dependence of the thermodynamic quantities and equation of state in the presence of rapid rotation and strong magnetic-field, at finite baryon chemical potential, is studied. Furthermore, the rotational and magnetic field dependence of conserved-charge susceptibilities and their correlations across the crossover region is examined. The thermodynamic quantities exhibit characteristic crossover behavior expected from lattice QCD.
