Charge response function probed by resonant inelastic x-ray scattering: the signature of electronic gaps of YBa $_{2}$ Cu $_{3}$ O $_{7 - δ}$

Giacomo Merzoni, Leonardo Martinelli, Lucio Braicovich +6

In strongly correlated systems the complete determination of the dynamical susceptibility $χ (q, ω)$ is of special relevance because of the entwinement of the spin and char…

Absence of localized $5 d^{1}$ electrons in KTaO $_{3}$ interface superconductors

Xinqiang Cai, Jungho Kim, Leonardo Martinelli +19

Recently, an exciting discovery of orientation-dependent superconductivity was made in two-dimensional electron gas (2DEG) at the interfaces of LaAlO $_{3}$ /KTaO $_{3}$ (LAO/KTO) or EuO/…

Doping-dependence of the electron-phonon coupling in two families of bilayer superconducting cuprates

Yingying Peng, Leonardo Martinelli, Qizhi Li +21

While electron-phonon coupling (EPC) is crucial for Cooper pairing in conventional superconductors, its role in high- $T_{c}$ superconducting cuprates is debated. Using resonant inela…

Polarization resolved Cu $L_{3}$ -edge resonant inelastic x-ray scattering of orbital and spin excitations in NdBa $_{2}$ Cu $_{3}$ O $_{7 - δ}$

R. Fumagalli, L. Braicovich, M. Minola +14

High resolution resonant inelastic x-ray scattering (RIXS) has proven particularly effective in the determination of crystal field and spin excitations in cuprates. Its strength li…
