Phys. Rev. A 79, 013834 (2009) [9 pages]Gravitational redshift and deflection of slow lightReceived 27 October 2008; published 30 January 2009 We explore the nature of the classical propagation of light through media with strong frequency-dependent dispersion in the presence of a gravitational field. In the weak field limit, gravity causes a redshift of the optical frequency, which the slow-light medium converts into a spatially varying index of refraction. This results in the bending of a light ray in the medium. We further propose experimental techniques to amplify and detect the phenomenon using weak value measurements. Independent heuristic and rigorous derivations of this effect are given. © 2009 The American Physical Society URL:
