    "abstract": "The liquid-gas phase transition in hot neutron-rich nuclear matter is\ninvestigated within a self-consistent thermal model using an isospin and\nmomentum dependent interaction (MDI) constrained by the isospin diffusion data\nin heavy-ion collisions, a momentum-independent interaction (MID), and an\nisoscalar momentum-dependent interaction (eMDYI). The boundary of the\nphase-coexistence region is shown to be sensitive to the density dependence of\nthe nuclear symmetry energy with a softer symmetry energy giving a higher\ncritical pressure and a larger area of phase-coexistence region. Compared with\nthe momentum-independent MID interaction, the isospin and momentum-dependent\nMDI interaction is found to increase the critical pressure and enlarge the area\nof phase-coexistence region. For the isoscalar momentum-dependent eMDYI\ninteraction, a limiting pressure above which the liquid-gas phase transition\ncannot take place has been found and it is shown to be sensitive to the\nstiffness of the symmetry energy.",
