Kohn–Luttinger effect and anomalous pairing in repulsive Fermi-systems at low density
In the large variety of models such as 3D and 2D Fermi-gas model with hard-core repulsion, 3D and 2D
 Hubbard model, and Shubin–Vonsovsky model we demonstrate the possibility of triplet p-wave pairing at low
 electron density. We show that the critical temperature of the p-wave pairi...

| description | In the large variety of models such as 3D and 2D Fermi-gas model with hard-core repulsion, 3D and 2D
Hubbard model, and Shubin–Vonsovsky model we demonstrate the possibility of triplet p-wave pairing at low
electron density. We show that the critical temperature of the p-wave pairing can be strongly increased in a spinpolarized
case or in a two-band situation already at low density and reach experimentally observable values of
(1–5) K. We also discuss briefly d-wave pairing and high-Tc superconductivity with Tc ~ 100 K which arises
in the extended Hubbard model and in the generalized t-J model close to half-filling.
