Abstract

A simple argument using a bosonization technique is presented to explain that superconducting strings have a net angular momentum carried by fermionic zero modes trapped on a string. The induced angular momentum is shown to be nonvanishing if the scalar phase field φ develops a kink along a string φ(+∞)-φ(-∞)≠0. .AE
