Pairing on Small Clusters in the Peierls-Hubbard Model: Implications for C$_{60}$
Abstract
We study the pairing within the Peierls-Hubbard Model for electron- and hole-doped analogs of C accessible to exact diagonalization techniques (cube, truncated tetrahedron, {\it etc.}). We discuss how inclusion of electron-phonon interactions can substantially modify the conclusions about pairing obtained when this coupling is neglected. We also discuss potential pitfalls in the extrapolation from these small system calculations to C, and stress the necessity of having the correct intuitive picture.
