Superconductivity in repulsive Fermi-systems at low density
M. Yu. Kagan, D. V. Efremov, M. S. Mar'enko +1
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 tri…
Anomalous resistivity and the electron-polaron effect in the two-band Hubbard model with one narrow band
M. Yu. Kagan, V. V. Val'kov
We search for anomalous normal and superconductive behavior in the two-band Hubbard model with one narrow band. We analyze the influence of electron-polaron effect and Altshuler-Ar…
Kinematic formation of the pseudogap spectral properties in a spatially homogeneous strongly correlated electron system
Valery V. Val'kov, Alexander A. Golovnya, Maxim M. Korovushkin
It is shown that the kinematic interaction caused by the quasi-Fermi character of commutation relations for operators of the atomic representation can induce pseudogap behavior of…
Fano Mechanism of the Giant Magnetoresistance Formation in a Spin Nanostructure
Valery V. Val'kov, Sergey V. Aksenov
It is shown that, upon the electron quantum transport via the nanostructure containing a spin dimer, the spin-flip processes caused by the s-f exchange interaction between electron…
Triplet p-wave superconductivity in low-density extended Hubbard model with Coulomb repulsion
M. Yu. Kagan, D. V. Efremov, M. S. Marienko +1
We analyze superconducting instabilities in 3D and 2D extended Hubbard model with Coulomb repulsion between electrons on neighboring sites in the limit of low electron density ($n_…
Anomalous resistivity and the origin of a heavy mass in the two-band Hubbard model with one narrow band
M. Yu. Kagan, V. V. Val'kov
We search for marginal Fermi-liquid behavior in the two-band Hubbard model with one narrow band. We consider the limit of low electron densities in the bands and strong intraband a…
