We consider the effect of strongly anisotropic turbulent mixing on the critical behavior of two systems: a Ï† critical dynamics model describing universal properties of metastable states in the vicinity of a firstorder phase transition and a reaction-diffusion system near the point of a...

Using the field theory renormalization group, we study the critical behavior of two systems subjected to turbulent mixing. The first system, described by the equilibrium model A, corresponds to the relaxational dynamics of a nonconserved order parameter. The second system is the strongly...

The renormalization group theory is used to the study of the directed bond percolation (Gribov process) near its second-order phase transition between absorbing and active state. We present a numerical calculation of the renormalization group functions in the Ïµ-expansion where Ïµ is the...

Steady, nonpropagating, fronts in reaction diffusion systems usually exist only for special sets of control parameters. When varying one control parameter, the front velocity may become zero only at isolated values (where the Maxwell condition is satisfied, for potential systems). The...

A mathematical model is presented which reproduces the experimental results of anisotropic front propagation in the bistable H[sub 2]+O[sub 2] reaction on a Rh(110) surface. A model represented by a system of two coupled nonlinear reaction-diffusion equations incorporates the chemical diffusion...

The interaction between the Turing instability and the instability induced by a differential flow is studied in the Selkov model. Both instabilities give rise to the formation of spatial patterns, and for a range of parameter values, these patterns can compete. The effect of anisotropic...
