Real-Space Interference from Quantum Metric
Bo-Qing Wu, Xing-Lei Ma, Jin-Xin Hu +2
Real-space interference of wave packets is governed by their central momentum separation and momentum width, which set the oscillation wavelength and spatial envelope, respectively…
Quantum Geometric Friedel Oscillations
Xing-Lei Ma, Jinchao Zhao, Bo-Qing Wu +2
In conventional Friedel oscillations, the real-space charge density oscillations induced by an impurity are characterized by an oscillation period set by the Fermi momentum. In thi…
Quantum Metric Localization and Quantum Metric Protection
Wen-Bo Dai, Jinchao Zhao, Shuai A. Chen +1
The study of disorder effects in electronic systems is one of the central themes in physics. It is well established that in the Anderson localization regime, the localization lengt…
Quantum Metric Bound State of Light
Jinchao Zhao, Rongning Liu, Xue-Yang Song +1
The spatial confinement of defect-induced bound states is conventionally governed by the effective mass in dispersive bands. More recently, Compact Localized States (CLSs) arising…
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…
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…
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-…
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…
Proof of a Stable Fixed Point for Strongly Correlated Electron Matter
Jinchao Zhao, Gabriele La Nave, Philip Phillips
We establish the Hatsugai-Kohmoto model as a stable quartic fixed point (distinct from Wilson-Fisher) by computing the function in the presence of perturbing local interactions…
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…
Exact solution for finite center-of-mass momentum Cooper pairing
Chandan Setty, Jinchao Zhao, Laura Fanfarillo +4
Pair density waves (PDWs) are superconducting states formed by ``Cooper pairs" of electrons containing a non-zero center-of-mass momentum. They are characterized by a spatially mod…
Thermodynamics of an Exactly Solvable Model for Superconductivity in a Doped Mott Insulator
Jinchao Zhao, Luke Yeo, Edwin Huang +1
Computing superconducting properties starting from an exactly solvable model for a doped Mott insulator stands as a grand challenge. We have recently shown that this can be done st…
