Bond stretching phonon softening and angle-resolved photoemission kinks in optimally doped Bi2Sr1 6La0.

Bond stretching phonon softening and angle-resolved photoemission kinks in optimally doped Bi2Sr1 [electronic resource] : 6La0.

We report the first measurement of the Cu-O bond stretching phonon dispersion in optimally doped Bi2Sr1.6La0.4Cu2O6+delta using inelastic x-ray scattering. We found a softening of this phonon at q=(0.25,0,0) from 76 to 60 meV, similar to the one reported in other cuprates. A comparison with angle-re...
