In this paper we intend to complement the identification given in Kuerten and Fernandes-Silva (Mod Phys Lett A 33:1850092, 2018) which relates the axion to a metric spinor phase by means of Maxwell’s theory in the Infeld-van der Waerden’s -formalism. Thus, we obtain two alternative identifications: The first focuses on Dirac’s theory so that when obtaining an axion-like phase-fermion coupling, we achieve the first identification, and the last one investigates the phase behavior under Peccei–Quinn rotations in order to show that the phase changes as an axion pseudoparticle. With the formal aspects established, we also study the semiclassical fermion-photon system to demonstrate that the magnetic monopole current defined in Kuerten and Fernandes-Silva (Mod. Phys. Lett. A. 33:1850092) has dyon charge in flat universe and acquires a Witten effect form when there is a demand for chiral symmetry.
