Interactions and excitations of nonabelian vortices. (English) Zbl 1050.81560
Summary: We examine bosonic zero modes of vortices formed in the gauge breaking \(G\to H\). For nonabelian \(G\), zero modes are generic. Their solutions depend on global symmetry structure. Vortices render the embedding \(H\subset G\) space dependent, with a dynamically determined subgroup \(\tilde H\) single valued. They Aharonov-Bohm scatter gauge bosons associated with multivalued generators. Alice strings \((H=\text{O}(2),\tilde H=\mathbb{Z}_ 2)\) attract charges and scatter SO(2) ‘photons,’ and a two-string system has zero modes with unlocalizable ‘Cheshire’ charge. The resulting superconductivity has novel electrodynamics.
