abstract = {The dynamical properties of a flexible dumbbell composed of
active Brownian particles are analytically analyzed. The
dumbbell is considered as a simplified description of a
linear active polymer. The two beads are independently
propelled in directions which change in a diffusive manner.
The relaxation behavior of the internal degree of freedom is
tightly coupled to the dumbbell activity. The latter
dominates the dynamics for strong propulsion. As is shown,
limitations in bond stretching strongly influence the
relaxation behavior. Similarly, under shear flow, activity
determines the relaxation and tumbling behavior at strong
propulsion. Moreover, shear leads to a preferred alignment
and consequently to shear thinning. Thereby, a different
power-law dependence on the shear rate compared to passive
dumbbells under flow is found.},
