Thomas-Fermi approximation to pairing in finite Fermi systems. The weak coupling regime
Thomas-Fermi approximation to pairing in finite Fermi systems. The weak coupling regime
We present a new semiclassical theory for describing pairing in finite Fermi systems. It is based on taking the ℏ → 0, i.e. Thomas-Fermi, limit of the gap equation written in the basis of the mean field (weak coupling). In addition to the position dependence of the Fermi momentum, the …
