Abstract

Results of Monte-Carlo simulations for the Falicov–Kimball (FK) model on a triangular lattice are presented. Half-filled neutral FK model on the triangular lattice is, at least in the large interaction regime, strongly frustrated. This results in disordered low-temperature impurity configurations. A pair distribution functions and frustrated-bond-graphs are used to quantitatively describe the formation of these states, when the temperature is lowered. The possibility of a phase transition is discussed.
