Reality and causality in quantum gravity modified electrodynamics

We present a general description of the propagation properties of quantum gravity modified electrodynamics characterized by constitutive relations up to second order in the correction parameter. The effective description corresponds to an electrodynamics in a dispersive and absorptive non-local medium, where the Green functions and the refraction indices can be explicitly calculated. The reality of the electromagnetic field together with the requirement of causal propagation in a given referrence frame leads to restrictions in the form of such refraction indices. In particular, absorption must be present in all cases and, contrary to the usual assumption, it is the dominant aspect in those effective models which exhibit linear effects in the correction parameter not related to birefringence. In such a situation absorption is linear while propagation is quadratical in the correction parameter.

Motivated by ideas about quantum gravity, a tremendous amount of effort over the past decade has gone into testing Lorentz invariance in various regimes. This review summarizes both the theoretical frameworks for tests of Lorentz invariance and experimental advances that have made new high precision tests possible. The current constraints on Lorentz violating effects from both terrestrial experiments and astrophysical observations are presented.

“…Finally we mention the use of astrophysical phenomena to discuss such modified theories. Distinguished examples are the bounds imposed by polarization measurements from astrophysical sources [43], the study of ultra high energy physics processes, among them cosmic rays, [44,45,46,48,49] and the consequences of the detected synchrotron radiation from the Crab nebulae, as well as that from other objects [21,22,69]. For recent reviews about such topics see Ref.…”

The old order of magnitude argument stating that physics from Planck scale is out of experimental reach has been reconsidered in recent years in the light of current astrophysical and high precision tests indicating possible enhancement of the otherwise tiny quantum gravity effects. Nowadays it seems feasible to probe and discard effects associated with some simplified models and situations describing the space time structure at Planck length by these means. In this work we intend to survey contributions that have been developed by at least one collaborator researcher working in México, but showing them within the whole framework of the field. The corresponding list of works start from Ref.[57] on. As in any paper of this kind an inevitable or even not adverted biased point of view can appear in spite of our efforts to avoid it. Clearly our list of references is incomplete and we apologize in advance for omissions due mainly to lack of space.
