摘要：

We study the photoemission and optical conductivity response of the strongly correlated metallic system CaxSr1-xVO3. We find that the basic features of the transfer of spectral weight in photoemission experiments and the unusual line shape 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 local impurity self-consistent approximation that is exact in the limit of large lattice connectivity.
