Inelastic neutron scattering investigations on optimally doped YBCO revealed a very pronounced temperature dependence in the Cu-O in-plane bond-stretching vibrations along the (010) direction: a shift of spectral weight by at least 10 meV has been observed in a narrow range of wave vectors halfway to the zone boundary. The temperature evolution starts at about 200 K, well above the superconducting transition temperature. The displacement pattern of the anomalous phonons indicates a dynamic one-dimensional charge-density modulation within the planes, but excludes a direct contribution from the Cu-O chains.
