abstract = {The properties of semiflexible polymers tethered by one end
to an impenetrable wall and exposed to oscillatory shear
flow are investigated by mesoscale simulations. A polymer,
confined in two dimensions, is described by a linear
bead-spring chain, and fluid interactions are incorporated
by the Brownian multiparticle collision dynamics approach.
At small strain, the polymers follow the applied flow field.
However, at high strain, we find a strongly nonlinear
response with major conformational changes. Polymers are
stretched along the flow direction and exhibit U-shaped
conformations while following the flow. As a consequence of
confinement in the half-space, frequency doubling in the
time-dependent polymer properties appears along the
direction normal to the wall},
