dc.descriptionSuperradiant scattering, which can be thought of as the wave analogue of the Penrose process is revisited. As is well-known, boson fields display superradiance provided they have frequency in a certain range whereas fermion fields do not. A succinct superradiance-checking algorithm employing particle number or energy current is formally reviewed and then applied to the case of fermion field. The demonstrations of the absence of fermionic superradiance in terms of the particle number current exist in the literature but they are in the context of two-component SL(2,C) spinor formalism for massive spinor and SO(3,1) Dirac spinor formalism for massless spinor. Here we present an alternative demonstration in terms of both particle number and energy current but in a different context of local SO(3,1) Dirac spinor formalism for both massless and massive spinors. It appears that our presentation confirms the absence of fermionic superradiance in a more simple and systematic manner.
