Generalized superconductors from the coupling of a scalar field to the Einstein tensor and their refractive index in massive gravity
Abstract We construct the generalized superconductors from the coupling of a scalar field to the Einstein tensor in the massive gravity and investigate their negative refraction in the probe limit. We observe that the larger graviton mass and Einstein tensor coupling parameters both hinder the forma...
