    Abstract

    We present the momentum evolution of collective charge modes in Sr14Cu24O41 over the complete Brillouin zone using inelastic resonant X-ray scattering. The observed spectrum is found to be dispersive with periodicity corresponding to the ladder sublattice for momentum transfers along the ladder "leg" direction, and nondispersive along the "rung". Details of the spectrum, including dispersion and linewidth, fall between characteristic charge spectra of single chain quasi-1D Mott insulators and quasi-2D cuprates.
