Two-eigenfunction correlation in a multifractal metal and insulator

E. Cuevas, V. E. Kravtsov

We consider the correlation of two single-particle probability densities $|{\Psi }_E(\mathbf{r}){|}^2$ at coinciding points $\mathbf{r}$ as a function of the energy separation $\omega =|E-E^{\prime }|$ for…
