Conditions are given which imply that certain non-autonomous analytic iterated function systems (NIFSs) in the complex plane C have uniformly perfect attractor sets, while other conditions th...

Abstract We present a new partially coherent source with spatiotemporal coupling. The stochastic light, which we call (ST) non-uniformly correlated (NUC) beam, combines space and time in an inhomogeneous (shift- or space-variant) correlation function. This results that self-focuses at controllable location space-time, making these beams potentially useful applications such as optical trapping, ...
