Dynamics of molecular shock-absorbers: energy dissipation and the Fluctuation Theorem
We study the non-equilibrium behaviour of piston-rotaxane molecules under compression and extension. These soft molecules consist of several free rings threaded onto a rod, with the position of one ring controlled by an external piston. A Langevin simulation shows that at a slow speed of compression and expansion, the force on the piston agrees well with the previously calculated equilibrium result. However at speeds larger than a characteristic speed, non-equilibrium effects become important,...[Show more]
