제목 Efficient Lattice Monte Carlo Method for Simulating Ring Polymers
초록 We applied a new, efficient Monte Carlo (MC) simulation method to investigate linear and ring polymers in densely packed melt states. The movement algorithm including four kinds of motions, comprised of end-bond motion, kink-jump motion, crankshaft motion and kink-diffusion motion, showed a faster equilibration as compared with the conventional method that includes three kinds of motions without the kink-diffusion for linear polymer melts. In comparison, for the ring polymers which do not have chain ends, we found that the addition of the kink-diffusion motion resulted in much faster relaxation in melt chains as compared with the results obtained with the two moves without the kink-diffusion. Therefore, this new MC method is ideally suited to investigate the equilibrium and dynamical properties of ring polymer melts of very high chain lengths.
