The Model Hamiltonian in Superconductivity Theory

  • N. N. Bogolyubov

Abstract

A system of fermions with attraction described by the model Hamiltonian in superconductivity theory with separable interaction is considered. Asymptotically exact estimates (as V → ∞) for the minimal eigenvalue of the Hamiltonian, correlation functions, and Green’s functions are obtained.
