Intermittent dissipation on fractal regions: the effect of non-localty
Abstract
In the past few years there has been a renewed interest about intermittent dynamics and complex patterns, and in particular about the concept of Self-Organization (SO) but under more realistic microphysical process than in the original presentation. In these systems, minor disturbances may lead to events called avalanches that can be produced in a wide range of scales. Furthermore, these events display fractal structure and power laws in their dynamics.
One such system is electric discharges where the dissipation occur in fractal regions and display power laws in parameters like current, charge, etc. The canonical model for SOC is the sandpile, which is governed by local interactions given by the difference of heights between neighbors. However, in the case of electric discharges, they are ruled by non-local effects due to the charges. In particular, we will study the fractal and intermittent dissipation in electrical discharges due to these non-local effects and to characterize their dynamics.- Publication:
