Renormalization Group for Directed Sandpile Models
نویسندگان
چکیده
Following the lead of earlier researchers, we construct a real space renormalization group map for a class of self-organized critical models. We then test a series of quantitative predictions implied by this map against direct simulations of various models. The theory passes four tests, but apparently fails a fifth. We also find that the map has an interesting nongeneric property, suggesting a deeper structure to the theory than previously appreciated. [S0031-9007(98)06840-9]

Dynamical real space renormalization group applied to sandpile models.
A general framework for the renormalization group analysis of self-organized critical sandpile models is formulated. The usual real space renormalization scheme for lattice models when applied to nonequilibrium dynamical models must be supplemented by feedback relations coming from the stationarity conditions. On the basis of these ideas the dynamically driven renormalization group is applied t...
متن کاملSandpile Dynamics and Renormalization-group Approach
A successful renormalization-group (RG) approach may provide signinicant insights of a system exhibiting power-law dependencies. In 1994, a RG scheme [1] was proposed for sandpile models which exhibit power-law behavior and function as the models of self-organized criticality [2]. One momentous result of such a RG approach is that BakTang-Wisenfeld (BTW) [2] sandpile posepossing a deterministic...
متن کاملModified renormalization strategy for sandpile models.
Following the renormalization-group scheme recently developed by Pietronero et al. [Phys. Rev. Lett. 72, 1690 (1994)] we introduce a simplifying strategy for the renormalization of the relaxation dynamics of sandpile models. In our scheme, five subcells at a generic scale b form the renormalized cell at the next larger scale. Now the fixed point has a unique nonzero dynamical component that all...
متن کاملRenormalization approach to the self-organized critical behavior of sandpile models.
We introduce a renormalization scheme of a type that is able to describe the self-organized critical state (SOC) of sandpile models. We have defined a characterization of the phase space that allows us to study the evolution of the dynamics under change of scale. In addition, a stationarity condition provides a feedback mechanism that drives the system to its critical state. We obtain an attrac...
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...
