Information and stochastic dynamics

Fluctuations and information in chemical networks

Stochastic dynamics

We study the stochastic dynamics of particles interacting with an external fluctuating field. This system may represent a membrane protein coupled to the membrane shape, or a colloid immersed in a binary mixture close to its critical point. Using analytical tools, we try to determine the effect of the external field on the particle dynamics.

We also study the correlations in systems of Brownian particles driven out of equilibrium, as an electrolyte under an electric field. We can write exact stochastic equations for the density fields of the different species, which can then be linearised to obtain the correlations.
