Applications and implications of fractional dynamics for dielectric relaxation

Abstract

This article summarizes briefly the presentation given by the author at the NATO Advanced Research Workshop on Broadband Dielectric Spectroscopy and its Advanced Technological Applications, held in Perpignan, France, in September 2011. The purpose of the invited presentation at the workshop was to review and summarize the basic theory of fractional dynamics (Hilfer, Phys Rev E 48:2466, 1993; Hilfer and Anton, Phys Rev E Rapid Commun 51:R848, 1995; Hilfer, Fractals 3(1):211, 1995; Hilfer, Chaos Solitons Fractals 5:1475, 1995; Hilfer, Fractals 3:549, 1995; Hilfer, Physica A 221:89, 1995; Hilfer, On fractional diffusion and its relation with continuous time random walks.

It was argued, that broadband dielectric spectroscopy might be useful to test effective field theories based on fractional dynamics. © 2013 Springer Science+Business Media Dordrecht.
