Exact analysis of the interplay of charge order and unconventional pairings in the 2D Hatsugai-Kohmoto model

Carlos Eduardo S. P. Corsino, Hermann Freire

We provide here a study of some competing ordering tendencies exhibited by the exactly solvable 2D Hatsugai-Kohmoto (HK) model on a square lattice. To this end, we investigate the…
