Thermal fluctuations in superconducting phases with chiral and symmetry on a triangular lattice
A. G. Groshev, A. K. Arzhnikov
The behavior of thermal fluctuations of a superconducting order parameter with extended and chiral symmetry is investigated. The study is carried out on a triangul…

Functional-integral approach to the investigation of the spin-spiral magnetic order and phase separation
Anatoly Arzhnikov, Andrey Groshev
We investigate a two-dimensional single-band Hubbard model with a nearest-neighbor hopping. We treat a commensurate collinear order as well as incommensurate spiral magnetic phases…
