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…

Incommensurate spin-density wave in two-dimensional Hubbard model
M. A. Timirgazin, A. K. Arzhnikov, A. V. Vedyayev
We consider the magnetic phase diagram of the two-dimensional Hubbard model on a square lattice. We take into account both spiral and collinear incommensurate magnetic states. The…
