Studies on Reaction-Diffusion Processes and Anomalous Kinetics

We investigate the behaviour of multimolecular reactions taking place on low dimensional and fractal substrates. In particular for trimolecular reactions (Schlogl model) we investigate the effects of spatial restriction on the steady state. We show that in d<2 the chemical system stabilises at a state far from equilibrium even without the presence of external sources.

Similarly for the Lattice Lotka-Volterra Model (LLV) and for the Lattice Limit-Cycle (LLC) model spatial restriction on 2-dimensional and fractal substrates changes the kinetics and leads to clustering phenomena and fractaly growing domains. Similar phenomena in chaotic dynamical systems are under investigation.
