Twisting the Hubbard model into the Momentum-Mixing Hatsugai-Kohmoto Model
Peizhi Mai, Jinchao Zhao, Gaurav Tenkila +4
The Hubbard model is a standard theoretical tool for studying materials with strong electron-electron interactions, such as the cuprate superconductors. Unfortunately, interaction-…

Solving the SU() Orbital Hatsugai-Kohmoto Model
Nico A. Hackner, Peizhi Mai, Philip W. Phillips
We show that the physics of the SU() Hubbard model can be realistically simulated with the recently developed orbital Hatsugai-Kohmoto model. In this approach, the momentum mixi…
