Equilibrium polymers
Participating group members: LaKedra Pam, Xinjiang Lü

A range of systems, including proteins like f-actin and wormlike micelles, exhibit reversible 1-dimensional association into polymers or polymer-like structures.  We have performed Monte Carlo simulations using a simplified equilibrium polymer model in which the strength of the associations and the rigidity of the chains can be easily varied.  Using this model, we can make predictions about the conditions required for the nematic orientational ordering of the chains and about chain length distributions.
