Collective behaviour of competing, coupled particles on a 1d chain — •Ines Weber1, Ludger Santen1, and Martin Evans2 — 1Department of Theoretical Physics, Saarland University, 66041 Saarbrücken, Germany — 2Department of Physics & Astronomy, University of Edinburgh, Edinburgh EH9 3JZ, UK
Biopolymers are dynamic filaments involved in a wide variety of biological processes such as intracellular transport. Experiments have shown them to exhibit non-equilibrium fluctuations and deformations induced by molecular motors. I will present a simple model of such processes, which comprises competing species of interacting particles on a lattice. They perform a `tug-of-war' and induce deformation and drift on a 1d chain. Constraints given by hard core coupling to next-neighbour sites influence the system's dynamics and result in collective particle behaviour.
