| contents | A remarkable feature of topological superconductors is the emergence of Majorana fermions in electron systems. Whereas the emergent Majorana fermions share the self-anti-particle property with Majorana fermions in particle physics, they may have essentially different electromagnetic properties. In this paper, we argue the electromagnetic response of spinful Majorana fermions in topological superconductors. We present a general theory of the electromagnetic response of spinful Majorana fermions in topological superconductors and clarify how the pairing symmetry is encoded in the electromagnetic response. As an application, we predict the sublattice-dependent dipole (Ising)-type magnetic response of corner Majorana fermions in iron-based superconductors. |
