Mechanisms of superconductivity and inhomogeneous states in metallic hydrogen and electron systems with attraction
M. Yu. Kagan, A. V. Krasavin, R. Sh. Ikhsanov +2
In the Review we discuss anomalous aspects of superconductivity (SC) and normal state, as well as formation of inhomogeneous (droplet-like or cluster-like) states in electron syste…

Software Complex for the Numerical Solution of the Isotropic Imaginary-Axis Eliashberg Equations
Renat Sh. Ikhsanov, Evgeny A. Mazur, Maxim Yu. Kagan
At present, the task of searching for compounds with a high superconducting transition temperature is a very relevant scientific direction. Usually, the calculation of is carried o…

Phase diagrams of polarized ultra-cold gases on attractive-U Hubbard ladders
E. Burovski, R. Sh. Ikhsanov, A. A. Kuznetsov +1
We consider a quasi-one-dimensional model of a two-component Fermi gas at zero temperature on one, two and three-leg attractive-U Hubbard ladders. We construct the grand canonical…
