Effect of thermal fuctuations on the nontrivial topology of the d+id superconducting phase
A. G. Groshev, A. K. Arzhnikov
The behavior of the topological index, characterizing the properties of superconducting phases of quasi-two-dimensional systems with nontrivial topology, is investigated depending…
Interplay of magnetism and superconductivity in 2D extended Hubbard model
V. F. Gilmutdinov, M. A. Timirgazin, A. K. Arzhnikov
The interplay between magnetic and superconducting states on a square lattice is studied using the extended Hubbard model, which takes into account the attraction of electrons loca…
Generalization properties of restricted Boltzmann machine for short-range order
M. A. Timirgazin, A. K. Arzhnikov
The restricted Boltzmann machine (RBM) is used to investigate short-range order in binary alloys. The network is trained on the data collected by Monte Carlo simulations for a simp…
Phase diagrams of singlet superconducting states with mixed symmetry
M. A. Timirgazin, V. F. Gilmutdinov, A. K. Arzhnikov
The competition between the singlet superconducting states with - and d-wave symmetry of the order parameter is studied within a single-band model with nearest-neighbor attracti…
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…
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…
