Bond stretching phonon softening and angle-resolved photoemission kinks in optimally doped Bi2Sr1.6La0.4Cu2O6 superconductors
J. Graf, M. d'Astuto, C. Jozwiak +7
We report the first measurement of the optical phonon dispersion in optimally doped single layer Bi2Sr1.6La0.4Cu2O6+delta using inelastic x-ray scattering. We found a strong soften…

Low-q dispersion of transverse acoustic phonons in YBaCuO
Andrea Gauzzi, Matteo D'Astuto, Francesca Licci +2
High-resolution (=1.3 meV) inelastic X-ray scattering (IXS) in optimally doped untwinned YBaCuO single crystals show that the dispersion of transverse acoustic…
