Machine-learning test of the single-ion model for excitations in cuprates
Maryia Zinouyeva, Leonardo Martinelli, Riccardo Arpaia +12
We investigate excitations in Resonant Inelastic X-ray Scattering spectra of YBaCuO and LaCuO using the local single-ion model. The data are analyzed by co…
Facet-selective ballistic supercurrent in a weak topological insulator
Prasanna Rout, Ankit Khola, Lalit Pandey +9
Topological superconductivity is widely pursued by inducing superconducting correlations in topologically protected boundary states. In two dimensions, this strategy has been reali…
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…
Boosting superconductivity in ultrathin YBaCuO films via nanofaceted substrates
Eric Wahlberg, Riccardo Arpaia, Debmalya Chakraborty +7
In cuprate high-temperature superconductors the doping level is fixed during synthesis, hence the charge carrier density per CuO plane cannot be easily tuned by conventional ga…
THz mixing of high-order harmonics using nanobridges
Núria Alcalde-Herraiz, Alessia Garibaldi, Karn Rongrueangkul +4
Superconducting materials are a key for technologies enabling a large number of devices including THz wave mixers and single photon detectors, though limited at very low temperatur…
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…
