Eikonal approximation, Finsler structures, and implications for Lorentz-violating photons in weak gravitational fields

M Schreck - Physical Review D, 2015 - APS
In the current article, the classical analog of the minimal photon sector in the Lorentz-
violating Standard-Model extension (SME) is investigated. The analysis is based on …
