Transport and Temperature: Exact spectrum and Drude weight 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, while exact analytical results for finite-temperature transpo…

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…

A mono-atomic orbital-based 1D topological crystalline insulator
Gengming Liu, Violet Workman, Jiho Noh +4
Topological crystalline insulators (TCIs) are classified by topological invariants defined with respect to the crystalline symmetries of their gapped bulk. The bulk-boundary corres…
