Correlation between optical phonon softening and superconducting in YBaCuO within -wave Eliashberg theory
Cunyuan Jiang, Giovanni A. Ummarino, Matteo Baggioli +2
We provide a mathematical description, based on d-wave Eliashberg theory, of the strong correlation between the experimentally observed softening of Raman modes associated with in-…
Constrains on s and d components of electron boson coupling constants in one band d wave Eliashberg theory for high Tc superconductors
Giovanni Alberto Ummarino
The phenomenology of overdoped high Tc superconductors can be described by a one band d wave Eliashberg theory where the mechanism of superconducting coupling is mediated by antife…
Strong-coupling d-wave superconductivity in PuCoGa_5 probed by point contact spectroscopy
D. Daghero, M. Tortello, G. A. Ummarino +7
A century on from its discovery, a complete fundamental understanding of superconductivity is still missing. Considerable research efforts are currently devoted to elucidating mech…
Large conductance modulation of gold thin films by huge charge injection via electrochemical gating
D. Daghero, F. Paolucci, A. Sola +5
By using an electrochemical gating technique with a new combination of polymer and electrolyte, we were able to inject surface charge densities n_2D as high as 3.5 \times 10^15 e/c…
Phononic Self energy effects and superconductivity in CaC
A. Sanna, S. Pittalis, J. K. Dewhurst +5
We study the graphite intercalated compound CaC by means of Eliashberg theory, focusing on the anisotropy properties. An analysis of the electron-phonon coupling is performed,…
Possible d+id scenario in La_{2-x}Sr_{x}CuO_4 by point-contact measurements
D. Daghero, R. S. Gonnelli, G. A. Ummarino +1
We analyze the results of point-contact measurements in La_{2-x}Sr_{x}CuO_{4} (LSCO) previously reported as a clear evidence of the separation between gap and pseudogap in this cop…
