Abstract

We study the photoemission and optical conductivity response of the strongly correlated metallic system $Ca_xSr_{1-x}VO_3$ . We find that the basic features of the transfer of spectral weight in photoemission experiments and the unusual lineshape of the optical response can be understood by modeling the system with a one band Hubbard model close to the Mott-Hubbard transition. We present a detailed comparison between the low frequency experimental data and the corresponding theoretical predictions obtained within the LISA method that is exact in the limit of large lattice connectivity.
