Doping dependence of density response and bond-stretching phonons in cuprates
Peter Horsch, Giniyat Khaliullin
Abstract
We explain the anomalous doping dependence of zone boundary (π,0) and (π,π) bond-stretching phonons in the high-temperature superconductor La2-δSrδCuO4 in the doping range 0<δ<0.35. Our calculations are based on a theory for the density response of doped Mott-Hubbard insulators.
