Polymer Braids and Iterated Moire Maps
摘要
Crystalline order in dense packings of long polymers with a definite handedness is difficult to reconcile with the tendency of these chiral objects to twist and braid about each other. If the chirality is weak, the state of lowest energy is a triangular lattice of rigid rods. When the chirality is strong, however, screw dislocations proliferate, leading to either a tilt grain boundary phase or a new "moire state" with twisted bond order. In the latter case, polymer trajectories in the plane perpendicular to their average direction are described by iterated moir\'e maps of remarkable complexity, reminiscent of dynamical systems.
