Re-entrant p-wave superconductivity in a Chern Dartboard Insulator

Yueyang Wu, Rebecca Chan, Taylor L. Hughes +1

We formulate an exact theory for a 2-band superconductor with inter-orbital pairing and band Hatsugai-Kohmoto (HK) interactions. We apply this theory to a Chern dartboard insulator…

Green-function Zeros Encode Competing Mott and Charge-ordering Scales

Peizhi Mai, Philip W. Phillips

While correlated insulators are devoid of low-energy quasiparticle poles, their Green functions retain clean momentum structure through zeros. However, precisely what zeros imply i…

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…

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…

The Luttinger Count is the Homotopy not the Physical Charge: Generalized Anomalies Characterize Non-Fermi Liquids

Gabriele La Nave, Jinchao Zhao, Philip W. Phillips

We show that the Luttinger-Ward functional can be formulated as an operator insertion in the path integral and hence can be thought of as a generalized symmetry. The key result is…

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…

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,…

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…

Dynamical Spectral Weight Transfer in the Orbital HK Model

Gaurav Tenkila, Jinchao Zhao, Philip W. Phillips

We compute explicitly the low-energy spectral weight (LESW) in the lower Hubbard band using the orbital Hatsugai-Kohmoto (OHK) model. We show that the dynamical mixing enters the L…

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-…

Nonlocal Conformal Field Theory

Bora Basa, Gabriele La Nave, Philip W. Phillips

Using the recently developed notion of a fractional Virasoro algebra, we explore the implied operator product expansions in nonlocal conformal field theories and their geometric me…
