First order phase transition in quark matter
Physical Review D
We investigate chiral phase transition of the first order in the quark matter. Using the Nambu-Jona-Lasinio model, an equation of state of the quark matter which is similar to the van der Waals' one is obtained. Moreover the specific heat and the compressibility are calculated. It is shown that they are enhanced in the symmetry broken phase, in particular diverge near the tricritical point.doi:10.1103/physrevd.70.114031 fatcat:z54urzwjtbbkdhzecfswslpvoy
