Nonuniversal Metallic Behavior of Superconducting Wires

Abstract
We calculate the low temperature resistance of a narrow superconducting wire associated with quantum mechanical phase slippage. Particular attention is payed to the effects of Coulomb interactions. Using a renormalization group approach, we obtain the temperature dependent resistance. The results show that, near the superconductor-insulator transition, the wire displays quasimetallic behavior characterized by a small but finite low temperature resistance.
