Low-energy effective theories of the two-thirds filled Hubbard model on the triangular necklace lattice

C. Janani, J. Merino, I. P. McCulloch +1

Motivated by Mo${}_3$S${}_7$(dmit)${}_3$, we investigate the Hubbard model on the triangular necklace lattice at two-thirds filling. We show, using second order perturbation theory, that…
