Dynamics of Starburst Dendrimers

Abstract

We report the calculation of autocorrelation relaxation times, intrinsic viscosity, and the diffusion coefficient of a starburst dendrimer model, using both the preaveraging and variational-bound techniques. The model includes hydrodynamic effects, represented by the Rotne−Prager interaction, as well as excluded-volume repulsion, represented by a hard-core potential. Analytical derivations of the main formulae used in the paper are all explicitly given, and Monte Carlo simulations are used to carry out the thermodynamic average.
