摘要：
The effective SU(2) chiral Lagrangian with external sources is given in the presence of nonvanishing nucleon densities by calculating the in-medium contributions of the chiral pion-nucleon Lagrangian. As a by-product, a relativistic quantum field theory for Fermi many-particle systems at zero temperature is directly derived from relativistic quantum field theory with functional methods.
