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…
