How Biology breaks down Einstein’s relation — •Jaques Prost — Ecole Supérieure de Physique et de Chimie Industrielles, Paris

One of the most important feature of Einstein analysis of Brownian motion, is the existence of a simple relation linking the diffusion contant of a particule to its friction coefficient. It’s generalization to more complex systems is the fluctuation dissipation theorem. I will review the different forms which living systems may use to break this theorem and how this breaking is related to biological function. The different developed examples will include molecular motors, out of equilibrium membranes and sensory systems.
