A Global Analog of Cheshire Charge

TL;DR

This paper demonstrates that models with spontaneously broken global symmetries can host defects similar to Alice strings and exhibit Cheshire charge exchange, with potential realization in superfluid He-3.

Contribution

It introduces a global analog of Cheshire charge and Alice strings, expanding understanding of topological defects in symmetry-broken systems.

Findings

Support for defects analogous to Alice strings in global symmetry models

Cheshire charge exchange process demonstrated in these models

Potential realization in superfluid He-3 suggested

Abstract

It is shown that a model with a spontaneously broken global symmetry can support defects analogous to Alice strings, and a process analogous to Cheshire charge exchange can take place. A possible realization in superfluid He-3 is pointed out.
