Charge order on a triangular lattice with Mott physics and arbitrary charge density
Aleksey Alekseev, Agnieszka Cichy, Konrad Jerzy Kapcia
Triangular-lattice systems attract a lot of attention due to various frustration-induced and strongly correlated effects. Here, we focus on the charge-ordering phenomenon by means…
Phase structure of the one-dimensional lattice gauge theory with second nearest-neighbor interactions
Yeimer Zambrano, Aleksey Alekseev, Konrad J. Kapcia +2
We investigate the ground-state phase diagram of a one-dimensional lattice gauge theory (LGT) model with hard-core bosons at half-filling, extending previous studies…
Particle-Hole Asymmetry and Pinball Liquid in a Triangular-Lattice Extended Hubbard Model within Mean-Field Approximation
Aleksey Alekseev, Agnieszka Cichy, Konrad Jerzy Kapcia
Recently, triangular lattice models have received a lot of attention since they can describe a number of strongly-correlated materials that exhibit superconductivity and various ma…
Suppression and revival of long-range ferromagnetic order in the multiorbital Fermi-Hubbard model
Andrii Sotnikov, Agnieszka Cichy, Jan Kuneš
By means of dynamical mean-field theory allowing for complete account of SU(2) rotational symmetry of interactions between spin-1/2 particles, we observe a strong effect of suppres…
