Constant rate linear interface depinning and self organized criticality
Alexei Vazquez, Oscar Sotolongo-Costa
The precise determination of the universality classes in self-organized critical phenomena (SOC) is still an unsolved problem. Different SOC models like sandpile, linear interface…
Universality in self-organized critical slope models
Alexei Vazquez, Oscar Sotolongo-Costa
The dynamics of critical slope self-organized critical models is studied, using a previous mapping into a linear interface depinning model dragged at one end. The model is solved o…
On the equivalence between the Barkhausen effect and directed Abelian sandpile models
Alexei Vazquez, Oscar Sotolongo-Costa
The existence of self-organized criticality in the Barkhausen effect and its analogy with sandpile models is investigated. It is demonstrated that a model recently introduced to de…
Force fluctuations in granular materials
Alexei Vazquez, Jose Marin-Antuña, O. Sotolongo-Costa
Force fluctuations in granular materials are investigated. A continuum equation is derived starting from a discrete model proposed in the literature. The influence of boundary cond…
Aging and Levy distributions in sandpiles
Oscar Sotolongo-Costa, Alexei Vazquez, J. C. Antoranz
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. Le…
