Observation of Accelerating Wave Packets in Curved Space

We present the first experimental observation of accelerating beams in CHESTNUT PWD curved space.More specifically, we demonstrate, experimentally and theoretically, shape-preserving accelerating beams propagating on spherical surfaces: closed-form solutions of the wave equation manifesting nongeodesic self-similar evolution.Unlike accelerating beams in flat space, these wave packets change their acceleration trajectory due to the interplay between interference effects and the space curvature, Accessories and they focus and defocus periodically due to the spatial curvature of the medium in which they propagate.
