Abstract

Phonon anomalies due to collective stripe modes in high Tc cuprates were demonstrated. These anomalies were observed mainly by neutron scattering experiments on La2-xSrxCuO4 (LSCO) and YBa2Cu3O6+x (YBCO) with various doping levels. The gapped branches of the phonon were found to be in-phase and out-of-phase oscillations relative to the charge collective mode. Results showed reconnection and gap formation in bands.
