Anomalous superconductivity and superfluidity in repulsive fermion systems
M. Yu. Kagan, V. A. Mitskan, M. M. Korovushkin
We discuss the mechanisms of unconventional superconductivity and superfluidity in 3D and 2D fermionic systems with purely repulsive interaction at low densities. We construct phas…
Magnetic mechanisms of pairing in strongly correlated electron system of copper oxides
S. G. Ovchinnikov, I. A. Makarov, E. I. Shneyder +3
The multielectron LDA+GTB approach has been developed to calculate electronic structure of strongly correlated cuprates. At low energies the effective Hamiltonian of the $t - t' -…
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…
Structural and Magnetic Characterization of Ni2MnBO5 ludwigite
Evgeniya Moshkina, Svetlana Sofronova, Alexey Veligzhanin +4
Single crystals of ludwigite Ni2MnBO5 were synthesized by flux growth technique. The detailed structural and magnetic characterizations of the synthesized samples have been carried…
Light trapping above the light cone in one-dimensional array of dielectric spheres
Evgeny N. Bulgakov, Almas F. Sadreev
We demonstrate bound states in the first TE and TM diffraction continua (BSC) in a linear periodic array of dielectric spheres in air above the light cone. We classify the BSCs acc…
