We find by Wilson numerical renormalization group and conformal field theory that a three-orbital Anderson impurity model for a C-60(n-) molecule has a very rich phase diagram which includes non-Fermi-liquid stable and unstable fixed points with interesting properties, most notably high sensitivity to doping n. We discuss the implications of our results to the conductance behavior of C-60-based single-molecule transistor devices.

Abstract

We find by Wilson numerical renormalization group and conformal field theory that a three-orbital Anderson impurity model for a C-60(n-) molecule has a very rich phase diagram which includes non-Fermi-liquid stable and unstable fixed points with interesting properties, most notably high sensitivity to doping n. We discuss the implications of our results to the conductance behavior of C-60-based single-molecule transistor devices.
