Michael Schluter (AT&T Bell Laboratories, Murray Hill, N.J.): "The electronic structure of fcc (face-centered cubic) alkali intercalated A3C60 (where A = K, Rb or Cs) is studied using the density functional (LDA) approach and a semi-empirical tight binding scheme fit to the results. The picture that emerges is one of tightly bound C60 molecules, weakly held together by narrow, almost dispersionless bands. These bands are part of a manifold, derived from a 1 = 5 set of states. The vibrational states of A3C60 are studied in a variety of models, reaching from simple Keating-type and...
