Dynamics of superconducting strings with chiral currents - art. no. 103513

We rederive, using an elementary formalism, the general solution to the equ ations of motion for a superconducting string with a chiral (null) neutral current, earlier obtained by Carter and Peter. We apply this solution to sh ow that the motion of such string loops is strictly periodic and analyze cu sp-like behavior and vorton solutions of arbitrary shape. We argue that thi s solution can be used to approximately describe the dynamics of supercondu cting strings with small non-chiral currents. We use this description to es timate the electromagnetic radiation power from such strings.
