【 摘 要 】

Analysis of optical conductivities measured for cuprates has been done via the doped Hubbard model in infinite dimensions using the analytical variant of the dynamic Lanczos method. We examine the frequency behavior in the low-frequency region at comparatively large doping, the midinfrared band, and the isobestic point in the optical conductivity of cuprates. We demonstrate that these features shown in infinite dimensions are the generic features of strong correlation.
