Sharp optical phonon softening close to optimal doping in La $_{2 - x}$ Ba $_{x}$ CuO $_{4 + δ}$

Matteo D'Astuto, Guy Dhalenne, Jeff Graf +6

We report a direct observation of a sharp Kohn-like anomaly in the doubly degenerate copper-oxygen bond-stretching phonon mode occurring at $q = (0.3, 0, 0)$ in La$_…

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…
