Correlation and phase-diffusion properties of coupled chemical oscillators. — •Amitabha Nandi and Benjamin Lindner — Max-Planck-Institut für Physik Komplexer Systeme, Nöthnitzer Str. 38 01187 Dresden, Germany.

We study two diffusively coupled Brusselator models by stochastic simulation and the corresponding chemical Langevin Equations. We investigate the diffusion of the phase difference between the two oscillators and also their correlation statistics. Diffusive coupling of the chemical oscillators introduces an elastic interaction term and a common noise term in the Langevin Equation for the coupled system. We investigate and compare the roles of these two distinct contributions to the correlation statistics of the oscillators.
