abstract = {The center-of-mass dynamics of star polymers in dilute
solution is analyzed by hybrid mesoscale simulations. The
fluid is modeled by the multiparticle collision dynamics
approach, a particle-based hydrodynamic simulation
technique, which is combined with molecular dynamics
simulations for the polymers. Star polymers of various
functionalities are considered. We determine the
center-of-mass velocity correlation functions, the
corresponding mean square displacements, and diffusion
coefficients. The velocity correlation functions exhibit a
functionality-dependent and structure-specific intermediate
time regime, with a slow decay. It is followed by the
long-time tail t −3/2, which is solely determined by the
fluid. Infinite-system-size diffusion coefficients are
determined from the velocity correlation function by a
combination of simulation and analytical results, as well as
from the center-of-mass mean square displacement for various
systems sizes and extrapolation. In terms of the
hydrodynamic radius, the star polymer hydrodynamic diffusion
coefficient exhibits the same universal system-size
dependence as a spherical colloid. The functionality
dependence of the ratio of hydrodynamic radii and the radii
of gyration agrees well with experimental predictions.},
