Abstract

We investigate the chiral symmetry restoration/breaking of a dense, magnetized and rotating quark matter within the Nambu Jona-Lasinio model including Nf=2N_f=2 and Nc=3N_c=3 numbers of flavors and colors, respectively. Imposing the spectral boundary conditions, as well as the positiveness of energy levels, lead to a correlation between the magnetic and rotation fields such that strongly magnetized plasma can not rotate anymore. We solve the gap equation at zero and finite temperature. At finite temperature and baryon chemical potential μB\mu_B, we sketch the phase diagrams Tc(μB)T_c(\mu_B) and Tc(RΩ)T_c(R\Omega) in different cases. As a result, we always observe inverse-rotational catalysis mean to decrease TcT_c by increasing RΩR\Omega. But the magnetic field has a more complex structure in the phase diagram. For slowly rotating plasma, we find that TcT_c decreases by increasing eBeB, while in the fast rotating plasma we see that TcT_c increases by increasing eBeB. Also, we locate exactly the position of Critical End Point by solving the equations of first and second derivatives of effective action with respect to the order parameters, simultaneously.
