Relaxation Dynamics of Macroscopic System

Spectral approaches to ageing

11th January 2006

Author: Bovier, A (Technische Universität Berlin)

Abstract

We investigate spectral characteristics of Markov chains that exhibit ageing. We consider two rather systems with rather different properties, Bouchaud's trap model and Sinai's random walk, and show how in both cases it is possible to obtain enough information on eigennvalues and eigenfunctions to deduce in an easy way all relevant dynamical properties.
