Autor: Götz Seibold, Riccardo Arpaia, Ying Ying Peng, Roberto Fumagalli, Lucio Braicovich, Carlo Di Castro, Marco Grilli, Giacomo Claudio Ghiringhelli, Sergio Caprara

Publikováno v: Communications Physics, Vol 4, Iss 1, Pp 1-6 (2021)

The strange metallic state of cuprates occurring in a broad region of their phase diagram outside the superconducting and pseudogapped regions remains a mystery. Here the authors consider the charge density fluctuations recently discovered in resonan

We use resonant inelastic x-ray scattering (RIXS) to investigate the magnetic dynamics of the infinite-layer cuprate CaCuO_{2}. We find that close to the (1/2,0) point, the single magnon decays into a broad continuum of excitations accounting for abo

Publikováno v: Physical Review Research, Vol 2, Iss 2, p 023231 (2020)

The coupling between lattice vibration quanta and valence electrons can induce charge-density modulations and decisively influence the transport properties of materials, e.g., leading to conventional superconductivity. In high-critical-temperature su

Publikováno v: Nanomaterials, Vol 10, Iss 4, p 817 (2020)

Epitaxial films of high critical temperature ( T c ) cuprate superconductors preserve their transport properties even when their thickness is reduced to a few nanometers. However, when approaching the single crystalline unit cell (u.c.) of thickness,

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

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 inelastic x-ray scattering at the oxygen $K$-edge, we studied the EPC in Bi

Thanks to high resolution and polarization analysis, resonant inelastic x-ray scattering (RIXS) magnetic spectra of La2CuO4, Sr2CuO2Cl2 and CaCuO2 reveal a rich set of properties of the spin 1/2 antiferromagnetic square lattice of cuprates. The leadi

Besides the mechanism responsible for high critical temperature superconductivity, the grand unresolved issue of the cuprates is the occurrence of a strange metallic state above the so-called pseudogap temperature $T^*$. Even though such state has be
