Anomalous superconductivity and unusual normal state properties of bilayer and twisted graphene (Brief review)
M. Yu. Kagan, M. M. Korovushkin, V. A. Mitskan +4
It has been shown that the Kohn--Luttinger superconductivity mechanism interplaying with other types of ordering can be implemented in systems with a hexagonal lattice. A number of…
High-T and Low-T Superconductivity in Electron Systems With Repulsion
Maxim Yu. Kagan, Vitaly A. Mitskan, Maxim M. Korovushkin
We demonstrate the instability of the normal state of purely repulsive fermionic systems towards the transition to the Kohn-Luttinger superconducting state. We construct the superc…
Effect of the long-range Coulomb interaction on phase diagram of the Kohn-Luttinger superconducting state in idealized graphene
M. Yu. Kagan, V. A. Mitskan, M. M. Korovushkin
The effect of the long-range Coulomb interaction on the realization of the Kohn-Luttinger superconductivity in idealized monolayer doped graphene is studied. It is shown that the a…
Hubbard fermions band splitting at the strong intersite Coulomb interaction
Valery V. Val'kov, Maxim M. Korovushkin
The effect of the strong intersite Coulomb correlations on the formation of the electron structure of the t-V-model has been studied. A qualitatively new result has been obtained w…
