Query: Effects of Alignment Activity on the Collapse Kinetics of a Flexible
  Polymer   Dynamics of various biological filaments can be understood within the
framework of active polymer models. Here we consider a bead-spring model for a
flexible polymer chain in which the active interaction among the beads is
introduced via an alignment rule adapted from the Vicsek model. Following a
quench from the high-temperature coil phase to a low-temperature state point,
we study the coarsening kinetics via molecular dynamics (MD) simulations using
the Langevin thermostat. For the passive polymer case the low-temperature
equilibrium state is a compact globule. Results from our MD simulations reveal
that though the globular state is also the typical final state in the active
case, the nonequilibrium pathways to arrive at such a state differ from the
passive picture due to the alignment interaction among the beads. We notice
that deviations from the intermediate "pearl-necklace"-like arrangement, that
is observed in the passive case, and the formation of more elongated
dumbbell-like structures increase with increasing activity. Furthermore, it
appears that while a small active force on the beads certainly makes the
coarsening process much faster, there exists nonmonotonic dependence of the
collapse time on the strength of active interaction. We quantify these
observations by comparing the scaling laws for the collapse time and growth of
pearls with the passive case.
