Electron Correlations and Electron-Lattice Coupling in C60
Recently it was found that C60-compounds become superconducting at temperatures which are high in comparison to other carbon compounds like doped graphite.1 The dependence of the superconducting transition temperature on lattice parameters and its insensitivity to different masses of the metal ions within the compound2,3 suggest that the origin of superconductivity must be connected with either anomalous electronic interactions or with a particular detail of electron-lattice coupling within the C60 molecules that sizeably differs from the one in graphite compounds.
