Abstract
We revisit the number theoretic division model of self-organized criticality [B. Luque et al.Phys. Rev. Lett. 101, 158702 (2008)10.1103/PhysRevLett.101.158702]. The model consists of a pool of M-1 ordered integers {2,3,⋯,M}, and the aim is to dynamically form a primitive set of integers, where no number can be divided or divisible by others. Using extensive simulation studies and finite-size scaling method, we find the primitive set size fluctuations in the division model to show power spectral density of the form 1/f^{α} in the frequency regime 1/M≪f≪1/2 with α≈2 (different from α≈1.80(1) as reported previously) along with an additional scaling in terms of the system size ∼M^{b}. We also show similar power spectra properties for a class of random walks with a power-law distributed jump size (Lévy flights).
期刊介绍:
Physical Review E (PRE), broad and interdisciplinary in scope, focuses on collective phenomena of many-body systems, with statistical physics and nonlinear dynamics as the central themes of the journal. Physical Review E publishes recent developments in biological and soft matter physics including granular materials, colloids, complex fluids, liquid crystals, and polymers. The journal covers fluid dynamics and plasma physics and includes sections on computational and interdisciplinary physics, for example, complex networks.
