“…Therefore, the QHPT is not of liquid-gas type. With the Clapeyron equation (35) one finds that this is due to the fact that the hadronic phase, which is less dense, has a lower entropy per baryon than the quark phase, s H < s Q (where we have replaced "I" by "H" and "II" by "Q"), which is opposite to the behavior in the LGPT. The negative slope of the p − T phase diagram makes the QHPT fundamentally different from the LGPT.…”

“…Such studies are also used to analyze the effect of model parameters on the QCD phase diagram [36][37][38][39]. The effect of different isospin/charge assumptions has been studied already extensively in the literature for the LGPT [35,[40][41][42][43][44][45], and also experimentally [46,47], and for the QHPT [36,38,48] as well. Some authors [43,45,[48][49][50] have stated that the LGPT and QHPT changes from first to second order (according to the Ehrenfest classification) if one goes to an asymmetric system.…”

Noncongruence of the nuclear liquid-gas and deconfinement phase transitions

First order phase transitions (PTs) with more than one globally conserved charge, so-called noncongruent PTs, have characteristic differences compared to congruent PTs (e.g., dimensionality of phase diagrams, location and properties of critical points and endpoints). In the present article we investigate the non-congruence of the nuclear liquid-gas PT at sub-saturation densities and the deconfinement PT at high densities and/or temperatures in Coulomb-less models, relevant for heavyion collisions and neutron stars. For the first PT, we use the FSUgold relativistic mean-field model and for the second one the relativistic chiral SU(3) model. The chiral SU(3) model is one of the few models for the deconfinement PT, which contains quarks and hadrons in arbitrary proportions (i.e. a "solution") and gives a continuous transition from pure hadronic to pure quark matter above a critical point. The study shows the universality of the applied concept of non-congruence for the two PTs with an upper critical point, and illustrates the different typical scales involved. In addition, we find a principle difference between the liquid-gas and the deconfinement PTs: in contrast to the ordinary Van-der-Waals-like PT, the phase coexistence line of the deconfinement PT has a negative slope in the pressure-temperature plane. As another qualitative difference we find that the non-congruent features of the deconfinement PT become vanishingly small around the critical point.

Effects of the liquid-gas phase transition and cluster formation on the symmetry energy

et al. 2014

Abstract. Various definitions of the symmetry energy are introduced for nuclei, dilute nuclear matter below saturation density and stellar matter, which it found in compact stars or core-collapse supernovae. The resulting differences are exemplified by calculations in a theoretical approach based on a generalized relativistic density functional for dense matter. It contains nucleonic clusters as explicit degrees of freedom with medium dependent properties that are derived for light clusters from a quantum statistical approach. With such a model the dissolution of clusters at high densities can be described. The effects of the liquidgas phase transition in nuclear matter and of cluster formation in stellar matter on the density dependence of the symmetry energy are studied for different temperatures. It is observed that correlations and the formation of inhomogeneous matter at low densities and temperatures causes an increase of the symmetry energy as compared to calculations assuming a uniform uncorrelated spatial distribution of constituent baryons and leptons.

“…It can be seen that for AV 18 potential with SCGF method and also for AV 18 + T NI potential with BHF method, the extracted critical temperatures are lower than those of our results. Among the results given by UV 14 + T NI, AV 14 and AV 14 + T NI potentials with the variational calculations and BlochDe Dominicis expansion, it is obvious …”

In this paper, we investigate the liquid gas phase transition for the spin polarized nuclear matter.Applying the lowest order constrained variational (LOCV) method, and using two microscopic potentials, AV 18 and U V 14 +TNI, we calculate the free energy, equation of state, order parameter, entropy, heat capacity and compressibility to derive the critical properties of spin polarized nuclear matter. Our results indicate that for the spin polarized nuclear matter, the second order phase transition takes place at lower temperatures with respect to the unpolarized one. It is also shown that the critical temperature of our spin polarized nuclear matter with a specific value of spin polarization parameter is in good agreement with the experimental result.1
