| 英文摘要 | We calculate the optical conductivity of La2-xSrxCuO4 in the inhomogeneous Hartree-Fock plus random phase approximation using the p-d model with parameters taken from first-principles calculations. The ground state evolves from a polaron state for small and moderate doping to a conventional metal for x greater than or similar to 1/4 in consistency with transport and optical experiments. The calculated optical conductivity shows good agreement with experiments regarding the peak positions and relative intensities for zero and small dopings. The precursor of the midinfrared band is identified with transitions from the localized states on Cu to the extended states above the Fermi level. |
