Spin polarized Skyrmions in the UEM(1) gauged Wess-Zumino action Original Research Article

We study the spin polarized Skyrmions coupled with the electromagnetic field through the gauged Wess-Zumino term. Configurations of the fields are obtained by variation with suitable boundary conditions. We find that the dipole magnetic field is generated by a circular current around the spin quantization axis of the soliton. This is understood on an analogy with the Meissner effect. The electric charge distributions turn out to have characteristic structures depending on the total charge of the soliton, which suggests the intrinsic deformation of baryons due to orbital motions of the constituents.
