Interplay between particle trapping and heterogeneity in anomalous diffusion
Haroldo V. Ribeiro, Angel A. Tateishi, Ervin K. Lenzi +2
Heterogeneous media diffusion is often described using position-dependent diffusion coefficients and estimated indirectly through mean squared displacement in experiments. This app…
Transient anomalous diffusion in heterogeneous media with stochastic resetting
M. K. Lenzi, E. K. Lenzi, L. M. S. Guilherme +2
We investigate a diffusion process in heterogeneous media where particles stochastically reset to their initial positions at a constant rate. The heterogeneous media is modeled usi…
Quenched and Annealed Disorder Mechanisms in Comb-Models with Fractional Operators
A. A. Tateishi, H. V. Ribeiro, T. Sandev +2
Recent experimental findings on anomalous diffusion have demanded novel models that combine annealed (temporal) and quenched (spatial or static) disorder mechanisms. The comb-model…
The role of fractional time-derivative operators on anomalous diffusion
Angel A. Tateishi, Haroldo V. Ribeiro, Ervin K. Lenzi
The generalized diffusion equations with fractional order derivatives have shown be quite efficient to describe the diffusion in complex systems, with the advantage of producing ex…
Anomalous diffusion in a symbolic model
H. V. Ribeiro, E. K. Lenzi, R. S. Mendes +1
We address this work to investigate some statistical properties of symbolic sequences generated by a numerical procedure in which the symbols are repeated following a power law pro…
