Linear and anomalous front propagation in system with non Gaussian diffusion: the importance of tails
Maurizio Serva, Davide Vergni, Angelo Vulpiani
We investigate front propagation in systems with diffusive and sub-diffusive behavior. The scaling behavior of moments of the diffusive problem, both in the standard and in the ano…
Reaction Spreading in Systems With Anomalous Diffusion
Fabio Cecconi, Davide Vergni, Angelo Vulpiani
We briefly review some aspects of the anomalous diffusion, and its relevance in reactive systems. In particular we consider {\it strong anomalous} diffusion characterized by the mo…
Reaction spreading on percolating clusters
Federico Bianco, Sergio Chibbaro, Davide Vergni +1
Reaction-diffusion processes in two-dimensional percolating structures are investigated. Two different problems are addressed: reaction spreading on a percolating cluster and front…
Reaction Spreading on Graphs
R. Burioni, S. Chibbaro, D. Vergni +1
We study reaction-diffusion processes on graphs through an extension of the standard reaction-diffusion equation starting from first principles. We focus on reaction spreading, i.e…
Combustion dynamics in steady compressible flows
S. Berti, D. Vergni, A. Vulpiani
We study the evolution of a reactive field advected by a one-dimensional compressible velocity field and subject to an ignition-type nonlinearity. In the limit of small molecular d…
Discreteness effects in a reacting system of particles with finite interaction radius
Stefano Berti, Cristobal Lopez, Davide Vergni +1
An autocatalytic reacting system with particles interacting at a finite distance is studied. We investigate the effects of the discrete-particle character of the model on propertie…
