RT Journal Article T1 Graviton-photon oscillation in alternative theories of gravity A1 Ruiz Cembranos, José Alberto A1 Coma Díaz, Mario A1 Martín Moruno, María Del Prado AB In this paper we investigate graviton-photon oscillation in the presence of an external magnetic field in alternative theories of gravity. Whereas the effect of an effective refractive index for the electromagnetic radiation was already considered in the literature, we develop the first approach to take into account the effect of the modification of the predictions for gravitational waves in alternative theories of gravity in the phenomenon of graviton-photon mixing.
