abstract = {The behavior of unknotted and trefoil-knotted ring polymers
under shear flow is here examined by means of mesoscopic
simulations. In contrast to most polymers, ring polymers in
a hydrodynamic solvent at high shear rates do not get
shortened in the vorticity direction. This is a consequence
of the backflow produced by the interaction of the sheared
solvent with the end-free polymer topology. The extended
structures of the ring in the vorticity-flow plane, when
they are aligned in a constant velocity plane, favor ring
contour fluctuations. This variety of conformations largely
suppresses the tank-treading type of rotation with extended
conformations in favor of the tumbling type of rotations,
where stretched and collapsed conformations alternate. The
extension of trefoil knots is also enhanced, so that the
knots become delocalized. We anticipate that these effects,
which disappear in the absence of hydrodynamic interactions,
will have a crucial impact on the rheological properties of
concentrated ring solutions, and will also influence the
behavior of more complicated systems such as mixtures of
polymers with different topologies.},
