Spin-fluctuation superconductivity in the Hubbard model
The theory of the superconductivity mediated by kinematic and exchange interactions in t−J and two-band Hubbard models in a paramagnetic state is formulated. The Dyson equations for the matrix Green functions in terms of the Hubbard operators are obtained in the non-crossing approximation. To ca...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The theory of the superconductivity mediated by kinematic and exchange
interactions in t−J and two-band Hubbard models in a paramagnetic state
is formulated. The Dyson equations for the matrix Green functions in terms
of the Hubbard operators are obtained in the non-crossing approximation.
To calculate superconducting Tc a numerical solution of self-consistent
Eliashberg equations is proposed. |
