“…In this communication we derive the most general equations of geometric optics in an arbitrarily curved space-time and for an arbitrary configuration of an axionic field. Our result generalises [14,15] to arbitrary space-times and we simplify the derivation presented in [16]. Another generalisation to light coupled to an axionic field and a cold nonmagnetized plasma in Minkowski space-time is presented in [17].…”

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.

“…Note that there are no non-linear couplings in this limit. It was shown in [15,17] that beyond the limit of geometric optics, higher orders in the coupling lead to spectral distortions and refractive phenomena show up.…”

“…However for our purposes it is more useful to instead find the different dispersion relations for left and right circular polarisations which cause this rotation as was done in a similar search for axions [17].

Domain walls arise in theories where there is spontaneous symmetry breaking of a discrete symmetry such as Z N and are a feature of many BSM models. In this work we consider the possibility of detecting domain walls through their optical effects and specify three different methods of coupling domain walls to the photon. We consider the effects of these couplings in the context of gravitational wave detectors, such as LIGO, and examine the sensitivity of these experiments to domain wall effects. In cases where gravitational wave detectors are not sensitive we examine our results in the context of axion experiments and show how effects of passing domain walls can be detected at interferometers searching for an axion signal.

The polarization of photons emitted by astrophysical sources might be altered as they travel through a dark matter medium composed of ultra light axion-like particles (ALPs). In particular, the coherent oscillations of the ALP background in the galactic halo induce a periodic change on the polarization of the electromagnetic radiation emitted by local sources such as pulsars. Building up on previous works, we develop a new, more robust, analysis based on the generalised Lomb-Scargle periodogram to search for this periodic signal in the emission of the Crab supernova remnant observed by the QUIJOTE MFI instrument and 20 Galactic pulsars from the Parkes Pulsar Timing Array (PPTA) project. We also carefully take into account the stochastic nature of the axion field, an effect often overlooked in previous works. This refined analysis leads to the strongest limits on the axion-photon coupling for a wide range of dark matter masses spanning 10 −23 eV m a 10 −19 eV. Finally, we survey possible optimal targets and the potential sensitivity to axionic dark-matter in this mass range that could be achieved using pulsar polarimetry in the future.
