Self-consistent solution to the nuclear many-body problem at finite temperature

The properties of symmetric nuclear matter are investigated within Green’s functions approach. We have implemented an iterative procedure allowing for a self-consistent evaluation of the single-particle and two-particle propagators. The in-medium scattering equation is solved for a realistic (nonseparable) nucleon-nucleon interaction including both particle-particle and hole-hole propagation. The corresponding two-particle propagator is constructed explicitly from the single-particle spectral functions. Results are obtained for finite temperatures and an extrapolation to $T=0\mathrm{}$ is presented.
