In-plane optical conductivity of La${}_{2-x}$Sr${}_x$CuO${}_4$: Reduced superconducting condensate and residual Drude-like response

S. Tajima, Y. Fudamoto, T. Kakeshita +5

Temperature dependences of the optical spectra of La${}_{2-x}$Sr${}_x$CuO${}_4$ with $x$=0.12 and 0.15 were carefully examined for a polarization parallel to the CuO${}_2$-plane over a wid…
