Abstract

An extensive analysis of strongly-interacting infinite Fermi systems is presented within the framework of the variational theory based on trial correlated wave functions. The Fermi hypernetted chain (FHNC) procedures for calculating the energy expectation value and other quantities of physical interest are derived in correspondence to the following two cases: (a) polarized Fermi systems described by Jastrow-Slater wave functions with state-independent correlation factors,(b)unpolarized Fermi systems described by Jastrow-type wave functions, with correlation factors depending on the spin-isospin state of the particles. Numerical results are presented for a simplified model of nuclear matter, for liquid 3He and for the hard-spheres Fermi system. The calculation of the surface energy coefficient for nuclear matter is also discussed.
