The spectrum of collective excitations of a modified model Hamiltonian of the BCS superconductivity theory
Description
The collective Hamiltonian of the BCS model of super conductivity is investigated in the infinite volume as a complete entity with the help of Green functions. It is established that the system cam be both in normal and superconductive states and the spectrum of collective excitations in the superconductive state is found
