| description |
A microscopic theory of electronic spectrum and superconductivity within the t-J model on the honeycomb lattice is formulated. The Dyson equation for the normal and anomalous Green functions for the two-band model
in terms of the Hubbard operators is derived by applying the Mori-type projection technique. The self-energy
is evaluated in the self-consistent Born approximation for electron scattering on spin and charge fluctuations
induced by the kinematical interaction for the Hubbard operators. Superconducting pairing mediated by the
antiferromagnetic exchange and spin fluctuations is discussed. |
