Spectral Function of Manganite Systems

ORAL

Abstract

Using a double exchange model with Jahn Teller distortions, we calculate the one particle spectral function of manganite systems. The relative contribution of the different interactions is established by means of Monte Carlo and self consistent mean field calculations. In particular, we examine the effects of electron-electron and electron-phonon couplings. We discuss the relevance of our results in relation to recent Photoemission experiments on layered manganites [1], where similarities of manganites spectra with that of cuprates was observed.\\[3pt] [1] N.
