Phys. Rev. E 70, 036118 (2004) [8 pages]Rapid self-organized criticality: Fractal evolution in extreme environmentsSee Also: Erratum Received 15 October 2003; revised 3 May 2004; published 28 September 2004 We introduce the phenomenon of rapid self-organized criticality (RSOC) and show that, like some models of self-organized criticality (SOC), RSOC generates scale-invariant event distributions and 1∕f noise. Unlike SOC, however, RSOC persists despite more than an order of magnitude variation in driving rate and displays extremely thick and dynamic branching geometry. Starting with an initial set of parameter values, we perform two numerical experiments in which nonequilibrium RSOC systems are tuned towards their critical points. The approach to the critical state is tracked using average branching rates, which must equal 1 if systems are genuinely critical. © 2004 The American Physical Society URL:
