| Summary: | A microscopic theory of electronic spectrum and superconducting pairing within the Hubbard model is formulated.
The Dyson equation for the normal and anomalous Green functions in terms of the Hubbard operators
is derived by applying the Mori-type projection technique. The self-energy is evaluated in the noncrossing
approximation for electron scattering on spin and charge fluctuations induced by kinematic interaction for
Hubbard operators. Numerical results for electron dispersion in the strong correlation limit are presented.
Superconducting pairing mediated by antiferromagnetic exchange and spin fluctuations is discussed. |
