High-Throughput GW Calculations via Machine Learning
Ragab. A. Abdelghany, Chih-En Hsu, Hung-Chung Hsueh +2
We present a machine learning (ML) framework that predicts quasiparticle energies across molecular dynamics (MD) trajectories with high accuracy and efficiency. Using only…
Correlated insulating states in slow Dirac fermions on a honeycomb moir{é} superlattice
Dongyang Yang, Jing Liang, Haodong Hu +8
Strong Coulomb repulsion is predicted to open a many-body charge gap at the Dirac point of graphene, transforming the semimetal into a Mott insulator. However, this correlated insu…
Phonon-mediated electron attraction in SrTiO via the generalized Fröhlich and deformation potential mechanisms
Christopher J. N. Coveney, Norm M. Tubman, Chih-En Hsu +6
Superconductivity in doped SrTiO was discovered in 1964, the first superconducting transition observed in a doped semiconductor. However, the mechanism of electron pairing in S…
Diverse Manifestations of Electron-Phonon Coupling in a Kagome Superconductor
Jing-Yang You, Chih-En Hsu, Mauro Del Ben +1
Recent angle-resolved photoemission spectroscopy (ARPES) experiments on a kagome metal CsVSb revealed distinct multimodal dispersion kinks and nodeless superconducting gaps…
