Decomposing momentum scales in the Hubbard Model: From Hatsugai-Kohmoto to Aubry-André
Dmitry Manning-Coe, Barry Bradlyn
The all-to-all momentum coupling of the Hubbard interaction makes interacting lattice models generically unsolvable. In many settings, however, from Peierls instabilities to Moiré…

Ground state stability, symmetry, and degeneracy in Mott insulators with long range interactions
Dmitry Manning-Coe, Barry Bradlyn
Recently, models with long-range interactions -- known as Hatsugai-Kohmoto (HK) models -- have emerged as a promising tool to study the emergence of superconductivity and topology…
