The crossover between the large and small polaron is discussed as a function of the electron-phonon coupling constant and the width of the electronic band. We apply the results to discuss some properties of the phase diagram of magnanites and cuprate superconductors in the normal state.

Abstract
The crossover between the large and small polaron is discussed as a function of the electron-phonon coupling constant and the width of the electronic band. We apply the results to discuss some properties of the phase diagram of magnanites and cuprate superconductors in the normal state.File in questo prodotto:
