Elimination of fast variables in stochastic nonlinear kinetics
(2020-08-21)
A reduced chemical scheme involving a small number of variables is often sufficient to account for the deterministic evolution of the concentration of the main species contributing to a reaction. However, its predictions ...
Scaling of submicrometric Turing patterns in concentrated growing systems
(American Physical Society, 2018-09-18)
The wavelength of a periodic spatial structure of Turing type is an intrinsic property of the considered reaction-diffusion dynamics and we address the question of its control at the microscopic scale for given dynamical ...
Stochastic approach to Fisher and Kolmogorov, Petrovskii, and Piskunov wave fronts for species with different diffusivities in dilute and concentrated solutions
(2020-11-15)
A wave front of Fisher and Kolmogorov, Petrovskii, and Piskunov type involving two species A and B with different diffusion coefficients and is studied using a master equation approach in dilute and concentrated solutions. ...
The FKPP wave front as a sensor of perturbed diffusion in concentrated systems
(American Physical Society, 2019-02-11)
The sensitivity to perturbations of the Fisher and Kolmogorov, Petrovskii, Piskunov front is used to find a quantity revealing perturbations of diffusion in a concentrated solution of two chemical species with different ...
