Saar Rahav (Technion) | Out of Equilibrium Dynamics of Molecular Machiness |
I will present a couple of examples for interesting out-of-equilibrium behaviors in models of molecular motors and machines. Certain artificial molecular machines can be modeled as time dependent master equations with thermally activated transitions. How should one change parameters in time to maximize the power output of such machines? Surprisingly, we find that the optimal driving protocol of such machines can be singular.
The operation of many molecular motors requires that certain molecules reach an active site and undergo a chemical reaction there. Resent results by the Henn and Kaplan groups (Biology, Technion) suggest that rate of arrival to the active site can be accelerated by additional inactive binding sites. We designed a simple model to investigate this effect. We found two mechanisms that allow an inactive site to (moderately) increase the reaction rate.
