Abstract
Directed collective motion in a circular array of unidirectionally
coupled oscillators with symmetric potential is obtained numerically in
the absence of external bias. This striking feature is interpreted as
the effect of the spontaneous breaking of temporal symmetry of the
coupling. It is revealed that a proper match of various control
parameters is important in generating an optimal coherent global
transport. Noise-sustained directed transport is also observed, and the
related stochastic resonance in an autonomous system is identified.
