The superconducting Fermi-liquid model including fermion bound states

In the present work a superconductivity theory is developed on the base of the Fermi-liquid model, including electron bound states above a superconducting transition temperature. It is shown that the phase transition is accompanied as a rule by the formation of Cooper pairs with obligatory formation...

Summary:In the present work a superconductivity theory is developed on the base of the Fermi-liquid model, including electron bound states above a superconducting transition temperature. It is shown that the phase transition is accompanied as a rule by the formation of Cooper pairs with obligatory formation of the bound state condensate. The transition temperature is determined as a function of the system's chemical potential and of the parameters characterizing both the interaction of the fermions with each other and their interaction with the bound states.
