Transport and Temperature 1: Exact spectrum and resistivity for the one-dimensional infinite- Hubbard model
Shuo Liu, Yuhao Ma, Hitesh J. Changlani +2
Understanding charge transport in strongly correlated systems remains a central challenge in condensed matter physics, particularly in light of the ubiquitous linear-in- resisti…
Universality of the Mott Transition
Jinchao Zhao, Peizhi Mai, Gaurav Tenkila +1
We demonstrate that the Mott transition exhibits universal scaling as a consequence of the breaking of a symmetry in momentum space. A direct consequence of this dis…
Charge Susceptibility and Kubo Response in Hatsugai-Kohmoto-related Models
Yuhao Ma, Jinchao Zhao, Edwin W. Huang +3
We study in depth the charge susceptibility for the band Hatsugai-Kohmoto (HK) and orbital (OHK) models. As either of these models describes a Mott insulator, the charge susceptibi…
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-…
Incipient quantum spin Hall insulator under strong correlations
Peizhi Mai, Jinchao Zhao, Philip W. Phillips
To assess prior mean-field claims that the interacting Kane-Mele model hosts a novel antiferromagnetic (AFM) Chern insulating phase for a wide range of sub-lattice potentials,…
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…
