“…The effect gives polarizationdependent trajectories for circularly polarized waves and leads to the splitting linearly polarized waves. The magnitude of the effect is inversely proportional to the frequency of the wave, depends on the curvature of spacetime, and has only recently been understood to full extent for Maxwell's equations [1308] and for linearized gravity [1309]. A similar treatment for the Dirac equation can be found in [1310], and a general overview can be found in [1311].…”

The exploration of the universe has recently entered a new era thanks to the multi-messenger paradigm, characterized by a continuous increase in the quantity and quality of experimental data that is obtained by the detection of the various cosmic messengers (photons, neutrinos, cosmic rays and gravitational waves) from numerous origins. They give us information about their sources in the universe and the properties of the intergalactic medium. Moreover, multi-messenger astronomy opens up the possibility to search for phenomenological signatures of quantum gravity. On the one hand, the most energetic events allow us to test our physical theories at energy regimes which are not directly accessible in accelerators; on the other hand, tiny effects in the propagation of very high energy particles could be amplified by cosmological distances. After decades of merely theoretical investigations, the possibility of obtaining phenomenological indications of Planck-scale effects is a revolutionary step in the quest for a quantum theory of gravity, but it requires cooperation between different communities of physicists (both theoretical and experimental). This review, prepared within the COST Action CA18108 "Quantum gravity phenomenology in the multi-messenger approach", is aimed at promoting this cooperation by giving a state-of-the art account of the interdisciplinary expertise that is needed in the effective search of quantum gravity footprints in the production, propagation and detection of cosmic messengers.

“…For example, the spin Hall effect which is normally studied in condensed matter field, is known to bring corrections to the geometrical optics limit in the case of light rays. Oancea et al 38 found an analogous effect for the gravitational optics and Andersson et al 39 found a similar effect for the gravitational waves. Similarly, the Aharonov-Bohm effect is known from quantum electromagnetism.…”

http://www.univ-lyon1.fr Each and every observational information we obtain from the sky regarding the brightnesses, distances or image distortions resides on the deviation of a null geodesic bundle. In this talk, we present the symplectic evolution of this bundle on a reduced phase space. The resulting formalism is analogous to the one in paraxial Newtonian optics. It allows one to identify any spacetime as an optical device and distinguish its thin lens, pure magnifier and rotator components. We will discuss the fact that the distance reciprocity in relativity results from the symplectic evolution of this null bundle. Other potential applications like wavization and its importance for both electromagnetic and gravitational waves will also be summarized.

“…Various approaches have been taken before to understand the motion of electromagnetic, and also gravitational, wave packets in this context. Some approaches have been based on classical high-frequency expansions in the spirit of geometric optics [36][37][38][39][40][41][42][43][44][45][46][47]. Others have taken a semiclassical approach, using the Bargmann-Wigner equations or Weyl equations [48][49][50].…”
