Quantum Geometric Friedel Oscillations
Xing-Lei Ma, Jinchao Zhao, Bo-Qing Wu +1
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…
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…
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…
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…
