Abstract
Electron correlation effects, which have attracted much interest after the discovery of high temperature superconductivity and manifest themselves in anomalous transport and/or magnetic phenomena, can also be found in optical properties of strongly correlated electron systems. In particular, we have recently discovered strong optical nonlinearity of one-dimensional (ID) Mott insulator Sr2CuO3, in near-infrared (IR) region.1
