Abstract

We study theoretically the physical properties of Rouse polymers when a subset of monomers along the backbone is subjected to an additional driving force of exponentially correlated fluctuating noise. In other words, the polymers are made up of two kinds of particle, one of which has an additional coupling to an active bath that subjects those particles to extra forces. We analyze properties of these active polymers, such as the end to end distance and the local structure induced by active kicks. We then proceed to quantify how the dynamics of such polymers depend on the proportion of monomers which are being actively driven, and show how the dynamics transitions from the normal Rouse like behavior to substantially faster dynamics. Finally we analyze some of the non-equilibrium properties induced in these systems, such as the irreversibility.
