Coupling of surface and volume dipole oscillations in C-60 molecules

Brack, Matthias ; Winkler, P ; Murthy, N


We first give a short review of the ``local-current approximation'' (LCA), derived from a general variation principle, which serves as a semiclassical description of strongly collective excitations in finite fermion systems starting from their quantum-mechanical mean-field ground state. We illustrate it for the example of coupled translational and compressional dipole excitations in metal ...
