Strong Light-Matter Interactions

We examine bosonic zero modes of vortices formed in the gauge breaking G\ensuremath{\rightarrow}H. For non-Abelian G, zero modes are generic. Their solutions depend on global symmetry structure. Vortices render the embedding H\ensuremath{\subset}G space dependent, with a dynamically determined subgroup H\ifmmode \tilde{}\else \~{}\fi{} single valued. They Aharonov-Bohm scatter gauge bosons associated with multivalued generators. Alice strings (H=O(2), H\ifmmode \tilde{}\else \~{}\fi{}=${\mathit{openZ}}_{2}$) 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.
