title: Observation of asymptotic localization of a wave packet.
abstract: We present the experimental observation of asymptotic localization, a new regime of wave packet localization under the action of an external linear potential gradient. We employ arrays of evanescently coupled waveguides and directly observe the wave packet trajectory, which exhibits an oscillation with vanishing amplitude and period.
