abstract = {We investigate structural and dynamical properties of
ultra-soft colloids in dilute and semi-dilute solutions by
hybrid mesoscale simulations under linear shear flow. In
particular, the influence of functionality on these
properties is addressed. Our study combines molecular
dynamics simulations for the solute with the multiparticle
collision dynamics approach for the coarse-grained solvent.
The star polymers exhibit large conformational and
orientational changes in shear flow, which we characterize
by the radius of gyration tensor and the alignment angle.
These quantities show a universal dependence on a
concentration- and functionality-dependent Weissenberg
number with slight deviations at high shear rates. Moreover,
the star polymers display a rotational dynamics with a
shear-rate- and concentration-dependent rotation frequency.
We attribute the concentration dependence to the screening
of hydrodynamic interactions in semi-dilute star-polymer
solutions.},
