Avalanche dynamics and nonexponential relaxation
Abstract
The theory of SOC, and related avalanche dynamics, is proposed as the origin of the ubiquitous nonexponential relaxation observed in complex systems. Introducing some scaling laws and relations we have obtained that the normalized relaxation function follows an stretched exponential decay and that the frequency spectrum follows a "1/f" noise. Moreover, in the MF aproach the relaxation is found to be exponential.
