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...
