In this paper we propose a very special relativity (VSR)-inspired description
of the axion electrodynamics. This proposal is based upon the construction of a
proper study of the SIM(2)--VSR gauge-symmetry. It is shown that the VSR
nonlocal effects give a health departure from the usual axion field theory. The
axionic classical dynamics is analysed in full detail, first by a discussion of
its solution in the presence of an external magnetic field. Next, we compute
photon-axion transition in VSR scenario by means of Primakoff interaction,
showing the change of a linearly polarized light to a circular one. Afterwards,
duality symmetry is discussed in the VSR framework.Comment: 16 pages; to appear in PL
