On the renormalization of the one-particle energies in a superfluid fermi system

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The fully renormalized energy gap equation is derived and expressed in terms of certain self-energy parts represented by generalized Feynman diagrams. Ladder approximation to the gap equation is given and discussed.

Riassunto

Si deduce l’equazione del gap energetico completamente rinormalizzata in funzione di alcune parti di autoenergia rappresentate da diagrammi di Feynman generalizzati. Si dà e si discute l’approssimazione a gradini all’equazione del gap.
