Image of FIG. 1.
FIG. 1.

Effective vacuum interaction in the Shubin-Vonsovsky model with Hubbard on-site repulsion U and additional Coulomb repulsion V at neighboring sites.

Image of FIG. 2.
FIG. 2.

Qualitative phase-diagram of the Shubin-Vonsovsky model in the strong coupling case. For n el = 1, an AFM state appears in the model, while for n el = 1/2 we have a checkerboard CO state. We have also extended regions of phase-separation close to n el = 1/ 2 and n el = 1.

FIG. 3.

A phase-separated state for densities 1/2 − δ c  < n el < 1/2 with nano-scale metallic clusters inside a CO checkerboard insulating matrix for V ≫ t.

Image of FIG. 4.
FIG. 4.

Polarization dependence of Tc in 3D case.

Image of FIG. 5.
FIG. 5.

Polarization dependence of Tc in 2D case.

Image of FIG. 6.
FIG. 6.

H-T diagram for 2D electron gas in parallel magnetic field.

Image of FIG. 7.
FIG. 7.

Tc as a function of relative filling in the two band model.

Image of FIG. 8.
FIG. 8.

The leading contribution to the effective interaction Veff for the p-wave pairing of heavy particles via polarization of light particles. The open circles stand for the vacuum T-matrix ThL , which in Born case coincides with interband Hubbard interaction UhL .

Image of FIG. 9.
FIG. 9.

The lowest order skeleton diagram for EPE in the self consistent T-matrix approximation. ThL sub stands for the T-matrix in matter.
