Compact and Stable Representation of Real-Frequency Spectral Functions for Machine Learning
Xinyang Dong, Ido Zemach, Lei Zhang +2
We introduce a compact and stable moment representation for real-frequency Green's functions, hybridization functions, and self-energies for machine-learning applications, avoiding…
Hybrid Hamiltonian-diagrammatic quantum impurity solver
Yang Yu, Gaurav Harsha, Lei Zhang +4
Quantum impurity models, which describe the coupling between interacting orbitals and a non-interacting bath, play a central role in the physics of strongly correlated electron sys…
Scalarization of charged Taub-NUT black hole and the entropy bound
Lei Zhang, Hai-Shan Liu
We investigate the spontaneous scalarization of charged Taub-NUT black holes within the framework of Einstein-Maxwell-scalar-Gauss-Bonnet gravity. By selecting a suitable coupling…
Thermal-Drift Sampling: Generating Thermal Ensembles for Learning Many-Body Systems
Jiyu Jiang, Mingrui Jing, Jizhe Lai +2
Thermal equilibrium states of many-body Hamiltonians are essential for probing quantum chaos, finite-temperature phases of matter, and training quantum machine learning models, yet…
