Metal-insulator transitions: Influence of lattice structure, Jahn-Teller effect, and Hund's rule coupling
J. E. Han, E. Koch, O. Gunnarsson
We study the influence of the lattice structure, the Jahn-Teller effect and the Hund's rule coupling on a metal-insulator transition in AnC60 (A= K, Rb). The difference in lattice…

Phonon spectral function for an interacting electron-phonon system
J. E. Han, O. Gunnarsson
Using exact diagonalzation techniques, we study a model of interacting electrons and phonons. The spectral width of the phonons is found to be reduced as the Coulomb interaction U…

Phonon line shape in disordered A3C60 (A= K, Rb)
J. E. Han, O. Gunnarsson, V. Eyert
We present a calculation of the Hg phonon self-energy for a model of A3C60 (A= K, Rb). The orientational disorder of the C60 molecules is included, and the lowest order self-energy…
