Machine-learning test of the single-ion model for $dd$ excitations in cuprates

Maryia Zinouyeva, Leonardo Martinelli, Riccardo Arpaia +12

We investigate $dd$ excitations in Resonant Inelastic X-ray Scattering spectra of YBa $_{2}$ Cu $_{3}$ O $_{6}$ and La $_{2}$ CuO $_{4}$ using the local single-ion model. The data are analyzed by co…

Unveiling the Interplay of Charge and Magnetic Excitations in HgBa $_{2}$ Ca $_{2}$ Cu $_{3}$ O $_{8 + δ}$

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…

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…
