Description
We discuss a dark photon model with successive symmetry breaking $\mathrm{SU(2)_D}$ $\to$ $\mathrm{U(1)_D}$ $\to$ $\mathbb{Z}_2$ in the dark sector. Various dark topological defects appear, such as monopoles, dyons, strings and beads. They are shown to induce QED electromagnetic fields through kinetic and magnetic mixing between $\mathrm{U(1)_{QED}}$ and $\mathrm{U(1)_D}$. In particular, dark beads appear from a distance to be particles with magnetic and electric charge, which we call pseudo-monopoles (dyons).
