Abstract:
The two-time temperature formalism is used to investigate the equilibrium properties of a normal Fermi gas in the presence of a small classical admixture whose interaction with the particles can be taken into account by solving the temperature equation for the "T-matrix" in the “scattering length” approximation. A characteristic temperature dependence is obtained
in the correction to the chemical potential and the specific heat of the system.
