Levy distribution of time delay in emission of resonantly trapped light in ferrodispersions

Abstract

Abstract. Time delays in emission of resonantly trapped light in magnetite microspheres dispersed in a ferrofluid were measured for three different sphere sizes. The time delay was found to vary randomly. The effect of the size of microspheres on the probability distribution was determined. Analysis of the data showed that the statistics of the time delay is best described by a Levy distribution.

Delay time of waves performing Lévy walks in 1D random media

“…Lévy statistics have been found in a broad range of contexts that go from foraging patterns of marine predators 22 to fluctuations of stock market indices 23 or resonant emission of light 24 . Lévy models are applied to describe anomalous diffusion of particles and waves that cannot be described by standard Brownian models [25][26][27][28][29][30][31][32] .…”
