Abstract
A two dimensional model of self-propelled particles combining both a
pause-and-go movement pattern and memory is studied in simulations. It
is shown, that in contrast to previously studied agent based models in
two dimensions, order and disorder are metastable states that can
co-exist at some parameter range. In particular, this implies that the
formation and decay of global order in swarms may be kinetic rather than
a phase transition. Our results explain metastability recently observed
in swarming locust and fish.
