Query: Low frequency spectroscopy of the correlated metallic system
  $Ca_xSr_{1-x}VO_3$   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.
