Collective Magnetic Excitations in a Photo-excited Electron-doped Cuprate Superconductor
Daniel Jost, Jiarui Li, Jordyn Hales +21
Elucidating the microscopic behavior of cuprates under ultrafast photoexcitation offers critical insights into their highly correlated out-of-equilibrium states. Although quasipart…
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-…
Photo-generated charge-transfer excitons in NiO revealed by ultrafast time-resolved resonant inelastic x-ray scattering
Giacomo Merzoni, Leonardo Martinelli, Sergii Parchenko +32
Strong electronic correlation can lead to insulating behavior and to the opening of large optical gaps, even in materials with partly filled valence shells. Although the non-equili…
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…
