Magnetic phase transitions and unusual antiferromagnetic states in the Hubbard model
M. A. Timirgazin, P. A. Igoshev, A. K. Arzhnikov +1
Ground state magnetic phase diagrams of the square and simple cubic lattices are investigated for the narrow band Hubbard model within the slave-boson approach by Kotliar and Rucke…
Pure Odd Frequency Superconductivity at the Cores of Proximity Vortices
Mohammad Alidoust, Alexander Zyuzin, Klaus Halterman
After more than a decade, direct observation of the odd frequency triplet pairing state in super- conducting hybrid structures remains elusive. We propose an experimentally feasibl…
Spiral magnetic order, non-uniform states and electron correlations in the conducting transition metal systems
P. A. Igoshev, M. A. Timirgazin, A. K. Arzhnikov +2
The ground-state magnetic phase diagram is calculated within the Hubbard and - exchange (Kondo) models for square and simple cubic lattices vs. band filling and interaction p…
Magnetoelectrics in Disordered Topological Insulator Josephson Junctions
I. V. Bobkova, A. M. Bobkov, Alexander A. Zyuzin +1
We theoretically study the coupling of electric charge and spin polarization in an equilibrium and nonequilibrium electric transport across a two dimensional Josephson configuratio…
Metal-Insulator Transition in the Hubbard Model: Correlations and Spiral Magnetic Structures
M. A. Timirgazin, P. A. Igoshev, A. K. Arzhnikov +1
The metal--insulator transition (MIT) for the square, simple cubic, and body-centered cubic lattices is investigated within the Hubbard model at half-filling by using both t…
Spiral magnetism in the single-band Hubbard model: the Hartree-Fock and slave-boson approaches
P. A. Igoshev, M. A. Timirgazin, V. F. Gilmutdinov +2
The ground-state magnetic phase diagram is investigated within the single-band Hubbard model for square and different cubic lattices. The results of employing the generalized non-c…
Correlation Effects and Non-Collinear Magnetism in the Doped Hubbard Model
P. A. Igoshev, M. A. Timirgazin, V. F. Gilmutdinov +2
The ground--state magnetic phase diagram is investigated for the two-- and three--dimensional -- Hubbard model. We take into account commensurate ferro--, antiferromagnetic,…
Coulomb drag between ballistic quantum wires
A. P. Dmitriev, I. V. Gornyi, D. G. Polyakov
We develop a kinetic equation description of Coulomb drag between ballistic one-dimensional electron systems, which enables us to demonstrate that equilibration processes between r…

Coulomb interaction in graphene: Relaxation rates and transport
M. Schuett, P. M. Ostrovsky, I. V. Gornyi +1
We analyze the inelastic electron-electron scattering in undoped graphene within the Keldysh diagrammatic approach. We demonstrate that finite temperature strongly affects the scre…
Scaling Behavior of Heavy Fermion Metals
V. R. Shaginyan, M. Ya. Amusia, A. Z. Msezane +1
Strongly correlated Fermi systems are fundamental systems in physics that are best studied experimentally, which until very recently have lacked theoretical explanations. This revi…

We consider the ground state magnetic phase diagram of the two-dimensional Hubbard model with nearest and next-nearest neighbor hopping in terms of electronic density and interacti…
Nonequilibrium kinetics of a disordered Luttinger liquid
D. A. Bagrets, I. V. Gornyi, D. G. Polyakov
We develop a kinetic theory for strongly correlated disordered one-dimensional electron systems out of equilibrium, within the Luttinger liquid model. In the absence of inhomogenei…
