Description

The insulating Mott state is formed due to repulsive electron-electron Coulomb interaction in the presence of the lattice (or in other words, due to electron-electron Umklapp processes). The second moment conductivity sum rule is derived, and it allows us to evaluate the strength of Umklapp scattering and the static electron-lattice energy. Mid-infrared spectra of current-current and density-density correlation functions in cuprates are suggested as evidence of strong Umklapp scattering
