Abstract:
During the last years, computer simulations have grown into a valuable investigation tool in the polymer physics field. Interacting potentials used in computer simulations are very important in providing realistic dynamics of macromolecules, but also fast simulations. We made comparison between efficacity of the interacting potentials used for Monte Carlo and molecular dynamics simulation of polymers. Using the reptation and generalized Verdier-Stockmayer algorithms, we made computer simulation for an isolated polymeric chain. We investigated the well-known model used in polymer physics: gaussian chain, pear necklace model, bead spring model and connected rigid bodies models.
