We study the phenomenon of internal avalanching within the context of recently proposed "Tetris" lattice models for granular media. We define a recycling dynamics under which the system reaches a steady state which is self-structured, i.e., it shows a complex interplay between textured internal structures and critical avalanche behavior. Furthermore, we develop a general mean-field theory for this class of systems and discuss possible scenarios for the breakdown of universality.

Abstract
We study the phenomenon of internal avalanching within the context of recently proposed "Tetris" lattice models for granular media. We define a recycling dynamics under which the system reaches a steady state which is self-structured, i.e., it shows a complex interplay between textured internal structures and critical avalanche behavior. Furthermore, we develop a general mean-field theory for this class of systems and discuss possible scenarios for the breakdown of universality.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
