Aging and Levy distributions in sandpiles

TL;DR

This paper investigates aging phenomena in sandpile models, revealing that relaxation dynamics depend on elapsed time and exhibit Levy distributions, suggesting a close link between aging and self-organized criticality.

Contribution

It demonstrates the presence of aging effects and Levy distributions in sandpile relaxation, highlighting a novel connection between aging and self-organized criticality in complex systems.

Findings

Relaxation depends on elapsed time since start.

Levy distributions characterize characteristic times.

Aging and self-organized criticality are closely related.

Abstract

Aging in complex systems is studied via the sandpile model. Relaxation of avalanches in sandpiles is observed to depend on the time elapsed since the begining of the relaxation. Levy behavior is observed in the distribution of characteristic times. In this way, aging and self-organized criticality appear to be closely related.
