abstract = {The conformational properties of flexible and semiflexible
polymers exposed to active noise are studied theoretically.
The noise may originate from the interaction of the polymer
with surrounding active (Brownian) particles or from the
inherent motion of the polymer itself, which may be composed
of active Brownian particles. In the latter case, the
respective monomers are independently propelled in
directions changing diffusively. For the description of the
polymer, we adopt the continuous Gaussian semiflexible
polymer model. Specifically, the finite polymer
extensibility is taken into account, which turns out to be
essential for the polymer conformations. Our analytical
calculations predict a strong dependence of the relaxation
times on the activity. In particular, semiflexible polymers
exhibit a crossover from a bending elasticity-dominated
dynamics to the flexible polymer dynamics with increasing
activity. This leads to a significant activity-induced
polymer shrinkage over a large range of self-propulsion
velocities. For large activities, the polymers swell and
their extension becomes comparable to the contour length.
The scaling properties of the mean square end-to-end
distance with respect to the polymer length and monomer
activity are discussed},
