Superconducting strings in the two-Higgs doublet model

arXiv:2410.03300 · doi:10.1016/j.physletb.2025.139714

Abstract

We present superconducting vortex solutions in the two-Higgs doublet model which has a gauged Higgs-family symmetry. We write down an ansatz for the solution and study its basic properties, for the case of both global and gauged symmetries. We demonstrate its prima-facie stability using 3D numerical simulations of a global version of the theory, observing the flow of current along the string. We discuss how generic such a phenomena might be and the possible consequences if such a model is found in nature.
