摘要
The frequency behavior of the generalized diffusion coefficient in both the metallic and insulating regions has been studied numerically within the self-consistent localization theory extended to include electron-electron interaction. The behavior of single-particle density of states near the metal-insulator transition is considered. The single-particle density of states is calculated taking into account the effect of electron-electron interaction on the generalized diffusion coefficient.
