| contents | In this contribution, we construct a supersymmetric extension of axionic electrodynamics by adopting the superspace/superfield approach. In terms of component fields, the resulting Lagrangian describes the interactions among the axion, the photon, and their respective supersymmetric partners, the axino and the photino. The model exhibits quartic fermionic couplings and self-couplings, as well as a non-polynomial interaction involving the axino, the photino, and a scalar partner of the axion. We also pay special attention to the dispersion relations in both the bosonic and fermionic sectors, and analyze the effective masses of the different particles. Finally, with the help of computational methods, we investigate the solutions to the bosonic field equations. As a result, we identify a class of axionic and electromagnetic-field configurations whose profiles resemble magnetic vortices. |
