Brownian Combustion Engines

Part of the Institute for Nonlinear Science book series (INLS)


Protein motors operate in a Brownian regime where inertia is negligible and thermal fluctuations are important. We show that, in this regime, symmetry breaking and time correlations suffice to generate motion and forces. We also show that a chemical cycle that gains energy while going around generates time correlations. Thus, we present a natural description of a system where the energy stored in chemical compounds can be transduced into motion.
