Phase diagram of quark-antiquark and diquark condensates at finite temperature and density in the 3-dimensional Gross Neveu model

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/200472We construct the phase diagrams of the quark-antiquark and diquark condensates at finite temperature and density in the 3D (dimensional) 2-flavor Gross Neveu model. We found that, in contrast to the case of the 4D Nambu Jona-Lasinio model, there is no region where the quark-antiquark and diquark condensates coexist. The phase diagrams obtained for some parameter region show similar structure with the 4D QCD phase diagram.15 pages, 3 figures; changed contentHigh Energy Physics - PhenomenologyPhase diagram of quark-antiquark and diquark condensates at finite temperature and density in the 3-dimensional Gross Neveu modeltext
