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,…
Fluctuating charge-density-wave correlations in the three-band Hubbard model
P. Mai, B. Cohen-Stead, T. A. Maier +1
The high-temperature superconducting cuprates host unidirectional spin- and charge-density-wave orders that can intertwine with superconductivity in non-trivial ways. While the cha…
Topological Phase Transition without Single-Particle-Gap Closing in Strongly Correlated Systems
Peizhi Mai, Jinchao Zhao, Thomas A. Maier +2
We show here that numerous examples abound where changing topology does not necessarily close the bulk insulating charge gap as demanded in the standard non-interacting picture. Fr…
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-…
