Query: Optical conductivity of overdoped cuprate superconductors: application
  to LSCO   We argue that recent measurements on both the superfluid density and the
optical conductivity of high-quality LSCO films can be understood almost
entirely within the theory of disordered BCS d-wave superconductors. The large
scattering rates deduced from experiments are shown to arise predominantly from
weak scatterers, probably the Sr dopants out of the CuO$_2$ plane, and
correspond to significant suppression of $T_c$ relative to a pure reference
state with the same doping. Our results confirm the "conventional" viewpoint
that the overdoped side of the cuprate phase diagram can be viewed as
approaching the BCS weak-coupling description of the superconducting state,
with significant many-body renormalization of the plasma frequency. They
suggest that, while some of the decrease in $T_c$ with overdoping may be due to
weakening of the pairing, disorder plays an essential role.
