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…

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…
