Query: Fermi-liquid theory of imbalanced quark matter   The temperature dependence of the thermodynamic potential of quantum
chromodynamics (QCD), the specific heat, and the quark effective mass are
calculated for imbalanced quark matter in the limit of a large number of quark
flavors (large-$N_F$), which corresponds to the random phase approximation.
Also a generalization of the relativistic Landau effective-mass relation in the
imbalanced case is given, which is then applied to this thermodynamic
potential.
