Rotational Phonons Drive Low-Energy Kinks in Cuprate Superconductors
Yanyong Wang, Manuel Engel, Christopher Lane +9
Angle-resolved photoemission spectroscopy (ARPES) reveals ubiquitous quasiparticle ``kinks'' near 70 meV and 40 meV across cuprate superconductors, often accompanied by…
Artificial Symmetry Breaking by Self-Interaction Error
Lin Hou, Cody Woods, Yanyong Wang +7
Symmetry is a cornerstone of quantum mechanics and materials theory, underpinning the classification of electronic states and the emergence of complex phenomena such as magnetism a…
Magnetism-Enhanced Strong Electron-Phonon Coupling in Infinite-Layer Nickelate
Ruiqi Zhang, Yanyong Wang, Manuel Engel +12
Intriguing analogies between the nickelates and the cuprates provide a promising avenue for unraveling the microscopic mechanisms underlying high- superconductivity. While ele…
Accurate Electron-phonon Interactions from Advanced Density Functional Theory
Yanyong Wang, Manuel Engel, Christopher Lane +9
Electron-phonon coupling (EPC) is key for understanding many properties of materials such as superconductivity and electric resistivity. Although first principles density-functiona…
