Abstract

States describing a non-zero number density of massive particles are investigated in the SU(2) chiral-invariant Gross-Neveu model. It is found that for a fixed positive density, the lowest energy state is color ferromagnetic, with all color spins aligned. For asymptotically large densities, the total energy and density are calculated as functions of the Fermi momentum. These quantities tend toward their counterparts in a non-interacting theory, with logarithmic corrections typical of an asymptotically free system. © 1982.
