We present a concise derivation of geometric optics in the presence of axionic fields in a curved space-time. Whenever light can be described via geometric optics (the eikonal approximation), the only difference to the situation without axionic field is the phenomenon of achromatic birefringence. Consequently, redshift of light and distance estimates based on propagating light rays, as well as shear and magnification due to gravitational lensing are not affected by the interaction of light with an axionic field.

  1. Spinoptics in the presence of axion-like particles in curved spacetime

    gr-qc 2026-07 accept novelty 6.5 of 10

    Spinoptics equations for axion–Maxwell theory yield helicity-dependent photon trajectory corrections from both spacetime curvature and arbitrary axion profiles.

  2. Geometric optics analysis in Lorentz violating Chern-Simons electrodynamics

    hep-ph 2025-01 reject novelty 4.0 of 10

    Geometric optics in the Maxwell-Carroll-Field-Jackiw theory gives a polarization rotation proportional to the integrated background vector, with the standard intensity transport equation unchanged.
