Title : Charge excitations in the t-J model. Possible implications for high-Tc cuprate superconductors

Abstract :
Motivated by the growing evidence of the importance of charge fluctuations in cuprates, we study the t-J model in a large-N expansion. We analyze all possible charge instabilities as well as the charge excitation spectrum for both, electron-doped and hole-doped Mott insulators. We discuss our results in the context of the recent x-rays experiments in cuprates.
