Regarding axion electrodynamics in the background flat FRW universe, we show that cosmological birefringence arises from an adiabatic noncyclic geometric phase that appears in the quantum state of photons because of their interaction with the axion field. We also show that the axion electrodynamics is equivalent to standard electrodynamics in time-dependent bi-isotropic magnetoelectric Tellegen media, which serves as an analogue system that can simulate cosmological birefringence.

First Constraint on Axion-Photon Coupling $g_{\gamma}$ from Neutron Star Observations
hep-ph 2025-06 reject novelty 6.0 of 10

The paper derives a first bound on the dimensionless axion-photon coupling gγ from pulsar polarization data, reporting |gγ|<0.93 at 1σ for axion masses below 10^-11 eV, via a neutron-star-induced axion field.
