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…
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…
Probing the Critical Point (CritPt) of AI Reasoning: a Frontier Physics Research Benchmark
Minhui Zhu, Minyang Tian, Xiaocheng Yang +61
While large language models (LLMs) with reasoning capabilities are progressing rapidly on high-school math competitions and coding, can they reason effectively through complex, ope…
Triplet Exciton-driven Topological Mott insulator at Finite Temperature
Peizhi Mai
Motivated by experiments in which the quantum anomalous Hall (QAH) charge gap greatly exceeds the Curie temperature, we apply determinantal quantum Monte Carlo to two complementary…
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,…
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-…
Particle-hole asymmetric ferromagnetism and spin textures in the triangular Hubbard-Hofstadter model
Jixun K. Ding, Luhang Yang, Wen O. Wang +8
In a lattice model subject to a perpendicular magnetic field, when the lattice constant is comparable to the magnetic length, one enters the "Hofstadter regime," where continuum La…
Failure of Topological Invariants in Strongly Correlated Matter
Jinchao Zhao, Peizhi Mai, Barry Bradlyn +1
We show exactly that standard `invariants' advocated to define topology for non-interacting systems deviate strongly from the Hall conductance whenever the excitation spectrum cont…
Robust charge-density wave correlations in the electron-doped single-band Hubbard model
Peizhi Mai, Nathan S. Nichols, Seher Karakuzu +4
There is growing evidence that the hole-doped single-band Hubbard and - models do not have a superconducting ground state reflective of the high-temperature cuprate supercond…
Evidence for chiral superconductivity on a silicon surface
F. Ming, X. Wu, C. Chen +9
Sn adatoms on a Si(111) substrate with 1/3 monolayer coverage form a two-dimensional triangular adatom lattice with one unpaired electron per site and an antiferromagnetic Mott ins…
1/4 is the new 1/2 when topology is intertwined with Mottness
Peizhi Mai, Jinchao Zhao, Benjamin E. Feldman +1
In non-interacting systems, bands from non-trivial topology emerge strictly at half-filling and exhibit either the quantum anomalous Hall or spin Hall effects. Here we show using d…
Topological Mott Insulator at Quarter Filling in the Interacting Haldane Model
Peizhi Mai, Benjamin E. Feldman, Philip W. Phillips
While the recent advances in topology have led to a classification scheme for electronic bands described by the standard theory of metals, a similar scheme has not emerged for stro…
Stripe correlations in the two-dimensional Hubbard-Holstein model
Seher Karakuzu, Andy Tanjaroon Ly, Peizhi Mai +3
Several state-of-the-art numerical methods have observed static or fluctuating spin and charge stripes in doped two-dimensional Hubbard models, suggesting that these orders play a…
Interaction-driven Spontaneous Ferromagnetic Insulating States with Odd Chern Numbers
Peizhi Mai, Edwin W. Huang, Jiachen Yu +2
Motivated by recent experimental work on moiré systems in a strong magnetic field, we compute the compressibility as well as the spin correlations and Hofstadter spectrum of spinfu…
Fluctuating intertwined stripes in the strange metal regime of the Hubbard model
Edwin W. Huang, Tianyi Liu, Wen O. Wang +6
Strongly correlated electron systems host a variety of poorly understood correlations in their high temperature normal state. Unlike ordered phases defined by order parameters, the…
Intertwined spin, charge and pair correlations in the two-dimensional Hubbard model in the thermodynamic limit
Peizhi Mai, Seher Karakuzu, Giovanni Balduzzi +2
The high-temperature superconducting cuprates are governed by intertwined striped magnetic and charge orders in addition to superconductivity. Remarkably similar behavior has also…
Pairing correlations in the cuprates: a numerical study of the three-band Hubbard model

We study the three-band Hubbard model for the copper oxide plane of the high-temperature superconducting cuprates using determinant quantum Monte Carlo and the dynamical cluster ap…
Orbital structure of the effective pairing interaction in the high-temperature superconducting cuprates
Peizhi Mai, Giovanni Balduzzi, Steven Johnston +1
The nature of the effective interaction responsible for pairing in the high-temperature superconducting cuprates remains unsettled. This question has been studied extensively using…
