Description
The effective chiral Lagrangian for cold dense nuclear matter is constructed, in which the chemical potential corresponding to the baryon number density of QCD is introduced and included in the effective Lagrangian as an external field. A nonperturbative approach inspired by chiral perturbation theory is employed to calculate the baryon number density and its susceptibility, pressure, and quark condensate. The relevant discussions of the obtained results are given.
