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…
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…
Ultrafast decoupling of polarization and strain in ferroelectric BaTiO
Le Phuong Hoang, David Pesquera, Gerard N. Hinsley +20
A fundamental understanding of the interplay between lattice structure, polarization and electrons is pivotal to the optical control of ferroelectrics. The interaction between ligh…
Superconductivity in PrNiO2 infinite-layer nickelates
Hoshang Sahib, Francesco Rosa, Aravind Raji +6
Several reports about infinite-layer nickelate thin films suggest that the superconducting critical temperature versus chemical doping phase diagram has a dome-like shape, similar…
