Dynamics of the intermediate state in a superconducting wire

Abstract

A new approach to the dynamics of the intermediate state in a wire is presented. It represents a generalization of a recent theory for the dynamic resistance of the wire. It is shown that a large dynamic self-inductance also appears. The effects of the wire's environment on the intermediate state dynamics are discussed for the first time, and the classical skin effect is accounted for to all orders. A detailed analysis of the ac voltage response to mixed dc and weak ac current conditions is presented.
