A simple diffusion model showing anomalous scaling
A number of iterated maps and one flow, which show chaotic behavior, have been studied numerically and their time evolution expressed in terms of higher-order moments Mm t . All the cases show anomalous behavior with Mm t tg m , with g m m. A simple analytic treatment is given based on an effective diffusion that is dependent on both space and time. This leads to a form for g m /m=a−b /m, which...
متن کاملAnomalous Knudsen Diffusion in Simple Pore Models
1. Introduction Gas diffusion in mesoporous media is often in the Knudsen regime, cross sections of the pores being considerably smaller than the intrinsic molecular mean free path. Coppens [1] predicted the effect of fractal wall roughness on Knudsen self-diffusivity K D in a channel. A " trapping " process was identified as the cause of reduction of
متن کاملStochastic models for relativistic diffusion.
The diffusion equation is related to the Schrödinger equation by analytic continuation. The formula E2=p2c2 + m2c4 leads to a relativistic Schrödinger equation, and analytic continuation yields a relativistic diffusion equation that involves fractional calculus. This paper develops stochastic models for relativistic diffusion and equivalent differential equations with no fractional derivatives....
متن کاملErgodic and Nonergodic Anomalous Diffusion in Coupled Stochastic Processes
Inspired by problems in biochemical kinetics, we study statistical properties of an overdamped Langevin process whose friction coefficient depends on the state of a similar, unobserved process. Integrating out the latter, we derive the long-time behavior of the mean square displacement. Anomalous diffusion is found. Since the diffusion exponent cannot be predicted using a simple scaling argumen...
متن کاملOptimal information diffusion in stochastic block models
We use the linear threshold model to study the diffusion of information on a network generated by the stochastic block model. We focus our analysis on a two-community structure where the initial set of informed nodes lies only in one of the two communities and we look for optimal network structures, i.e., those maximizing the asymptotic extent of the diffusion. We find that, constraining the me...
