Spectral approaches to ageing

Wednesday 11th January 2006 - 09:50 to 10:40
INI Seminar Room 1

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.
