Aging exponents in self-organized criticality
In a recent Letter @Phys. Rev. Lett. 79, 889 ~1997!# we demonstrated that the avalanches in the Bak-Sneppen model display aging behavior similar to glassy systems. Numerical results for temporal correlations show a broad distribution with two distinct regimes separated by a time scale that is related to the age of the avalanche. This dynamical breaking of time-translational invariance results i...

متن کاملSelf-Organized Criticality
The causes and possible relations between the abundance of fractal structures and 1/f signals found in nature have puzzled scientists for years. Based on observations of computer simulations of the cellular automata sandpile model, the term, self-organized criticality (SOC) was invented by theoretical physicists Bak and coworkers (1987) and was used to explain a universal dynamic organizing pro...
متن کاملSelf-organized criticality
We study the concept of the self-organized criticality (SOC) and its application to a wide range of scientific problems with very different backgrounds. In particular, we discuss the Bak-TangWiesenfeld sandpile model which displays SOC behavior and by computing the critical exponent for the two-dimensional model we find the agreement with the known result. Finally, we provide a new example of Z...
متن کاملSelf-Organized Criticality
The concept of self-organized criticality (SOC) has been evoked by Bak, Tang and Wiesenfeld (BTW) as a possible unifying framework to describe a vast class of dynamically driven systems which evolve spontaneously toward a critical stationary state with no characteristic time or length scale. In this essay we will discuss SOC models that have been studied and to what extent they are related to r...
