报告简介:
In polymer simulations related to structure formation and phase separation, the polymer chains have to move a large distance to form domains at nanoscale or even larger. Due to large molecular size and slow relaxation of the polymer chains, a great amount of issues related to long-distance chain displacement cannot be tackled easily with conventional molecular dynamic simulations. We therefore have to consider the systematic coarse-graining and enhanced sampling so that we can access to equilibrium structures of phase separation or self-assembly in polymer simulations. A stochastic reaction model coupled with coarse-grained simulations will be used to cope with the problems influenced by the coupling of polymerization and chain diffusion. We have also developed a GPU-accellerated molecular simulation tookit for use in coarse-grained simulations of polymer systems with several unique simulation tools implemented.
