Query: Superconducting Instability in a 1D lattice of Berry Phase Molecules   We study the 1D model of conduction electrons interacting with local vibronic
modes. States in the conduction band are two-fold degenerate both in orbital
index and spin. It is shown that such 1D system has a strong tendency to
superconductivity. The superconducting pairing originates from coupling of two
charge density waves; the scaling dimension of the order parameter is close to
1/4.
