Methodology of a self-consistent Green's functions approach in nuclear matter at finite temperature.

摘要

An implementation of self-consistent Green's functions in nuclear matter at finite temperature is detailed. The nucleon/nucleon potential is a Reid hard-core potential. The ansatz for this approach is previous self-consistent self energies at the same temperature (5 MeV). From those self energies, a set of spectral functions is derived, and parametrized. Parametrization consists of nineteen independent parameters that can be fit using a unique fitting tool that is also discussed. This ansatz is extended to high momentum and iterated.
