TL;DR: Analogous gravity is a research programme which investigates analogues of general relativistic gravitational fields within other physical systems, typically but not exclusively condensed matter systems, with the aim of gaining new insights into their corresponding problems.

TL;DR: In this article, the authors consider the possibility of quantum gravity induced violation of Lorentz symmetry (LV) and present a number of new results which include the explicit computation of rates of the most relevant LV processes, derivation of a new photon decay constraint, and modification of previous constraints taking proper account of the helicity dependence of the LV parameters implied by effective field theory.

TL;DR: In this paper, the authors present an updated review of Lorentz invariance tests in effective field theories (EFTs) in the matter as well as in the gravity sector.

TL;DR: A comprehensive overview of the state of the art in the relevant fields of research, summarize important open problems, and lay out a roadmap for future progress can be found in this article, where the authors present a concise, yet comprehensive overview.
