Machine-learning test of the single-ion model for excitations in cuprates
Maryia Zinouyeva, Leonardo Martinelli, Riccardo Arpaia +12
We investigate excitations in Resonant Inelastic X-ray Scattering spectra of YBaCuO and LaCuO using the local single-ion model. The data are analyzed by co…
Collective Magnetic Excitations in a Photo-excited Electron-doped Cuprate Superconductor
Daniel Jost, Jiarui Li, Jordyn Hales +21
The study uses time‑resolved resonant inelastic X‑ray scattering to monitor how collective magnetic excitations (paramagnons) in an optimally electron‑doped cuprate superconductor…
Unveiling the Interplay of Charge and Magnetic Excitations in HgBaCaCuO
Karn Rongrueangkul, Martina Fedele, Leonardo Martinelli +10
Unraveling the mechanism that binds electrons into Cooper pairs in cuprate high-temperature superconductors remains one of the most fundamental challenges in condensed-matter physi…
Spin and orbital excitations in undoped infinite layers: a comparison between superconducting PrNiO2 and insulating CaCuO2
Francesco Rosa, Hoshang Sahib, Giacomo Merzoni +9
Infinite-layer nickelates are among the most promising cuprate-akin superconductors, although relevant differences from copper oxides have been reported. Here, we present momentum-…
Electron-phonon coupling revealed by charge density fluctuations in cuprate superconductors
Martina Fedele, Giacomo Merzoni, Marco Moretti Sala +6
Electron-phonon coupling (EPC) governs lattice dynamics, charge transport, and collective electronic phases in quantum materials. In several families of unconventional superconduct…
The influence of phonon symmetry and electronic structure on the electron-phonon coupling momentum dependence in cuprates
Maryia Zinouyeva, Rolf Heid, Giacomo Merzoni +16
The experimental determination of the magnitude and momentum dependence of electron-phonon coupling (EPC) is an outstanding problem in condensed matter physics. The intensity of ph…
