Mobility of semi-flexible chains coupled with hydrodynamics — •Won Kyu Kim and Roland Netz — Freie Universität Berlin, Arnimallee 14, 14195 Berlin, Germany

We study the hydrodynamic coupling and the effect of fluctuations on semi-flexible chains propulsion dynamics, where the chains are externally driven by an oscillating force or torque. By use of the linear response theory and Brownian dynamics simulations, we find optimal conditions for the chain propulsive force which can be maximized by proper driving frequencies and chain flexibilities. And we discuss how can the chain dynamics attain the effective propulsion in a collective manner.
