Realistic and effective interactions in the study of nuclear matter

Abstract

The equation of state of symmetric nuclear matter is addressed starting both from a realistic interaction derived from nucleon-nucleon scattering processes and from a low-momentum effective potential. The approach is based on finite temperature Green's functions. The internal energy per particle is estimated from the summation of diagrams and through the Galitskii-Koltun's sum rule.
