Anomalous excitonic phase diagram in band-gap-tuned Ta2Ni(Se,S)5
Cheng Chen, Weichen Tang, Xiang Chen +17
During a band-gap-tuned semimetal-to-semiconductor transition, Coulomb attraction between electrons and holes can cause spontaneously formed excitons near the zero-band-gap point,…
A unique van Hove singularity in kagome superconductor CsVTaSb with enhanced superconductivity
Yang Luo, Yulei Han, Jinjin Liu +23
Van Hove singularity (VHS) has been considered as a driving source for unconventional superconductivity. A VHS in two-dimensional (2D) materials consists of a saddle point connecti…
Prevailing charge order in overdoped cuprates beyond the superconducting dome
Qizhi Li, Hsiao-Yu Huang, Tianshuang Ren +14
The extremely overdoped cuprates are generally considered to be Fermi liquid metals without exotic orders, whereas the underdoped cuprates harbor intertwined states. Contrary to th…
Role of electron-phonon coupling in excitonic insulator candidate Ta2NiSe5
Cheng Chen, Xiang Chen, Weichen Tang +15
Electron-hole bound pairs, or excitons, are common excitations in semiconductors. They can spontaneously form and ``condense'' into a new insulating ground state -- the so-called e…
Higher-Order Spin-Hole Correlations around a Localized Charge Impurity
Yao Wang, Annabelle Bohrdt, Joannis Koepsell +2
Analysis of higher-order correlation functions has become a powerful tool for investigating interacting many-body systems in quantum simulators, such as quantum gas microscopes. Ex…
Sionnx: Automatic Unit Test Generator for ONNX Conformance
Xinli Cai, Peng Zhou, Shuhan Ding +2
Open Neural Network Exchange (ONNX) is an open format to represent AI models and is supported by many machine learning frameworks. While ONNX defines unified and portable computati…
