Abstract

We argue that as a consequence of gauge invariance, if the lowest energy excitations of a system are fractionally charged, they must be described by a multivalued wave function. We interpret this to mean that they carry non-local information (such as a string) with them. We discuss two examples: (1) the fractionally charged solitons that arise in certain (1+1)-dimensional systems; (2) the fractional quantum Hall effect.
