      abstract     = {The collective behavior of active semiflexible filaments is
                      studied with a model of tangentially driven self-propelled
                      worm-like chains. The combination of excluded-volume
                      interactions and self-propulsion leads to several distinct
                      dynamic phases as a function of bending rigidity, activity,
                      and aspect ratio of individual filaments. We consider first
                      the case of intermediate filament density. For
                      high-aspect-ratio filaments, we identify a transition with
                      increasing propulsion from a state of free-swimming
                      filaments to a state of spiraled filaments with nearly
                      frozen translational motion. For lower aspect ratios, this
                      gas-of-spirals phase is suppressed with growing density due
                      to filament collisions; instead, filaments form clusters
                      similar to self-propelled rods. As activity increases,
                      finite bending rigidity strongly effects the dynamics and
                      phase behavior. Flexible filaments form small and transient
                      clusters, while stiffer filaments organize into giant
                      clusters, similarly to self-propelled rods, but with a
                      reentrant phase behavior from giant to smaller clusters as
                      activity becomes large enough to bend the filaments. For
                      high filament densities, we identify a nearly frozen jamming
                      state at low activities, a nematic laning state at
                      intermediate activities, and an active-turbulence state at
                      high activities. The latter state is characterized by a
                      power-law decay of the energy spectrum as a function of wave
                      number. The resulting phase diagrams encapsulate tunable
                      non-equilibrium steady states that can be used in the
                      organization of living matter.},
