Directing transport by polarized radiation in the presence of chaos and dissipation

We study numerically the dynamics of particles on the Galton board of semidisk scatters in the presence of monochromatic radiation and dissipation. It is shown that under certain conditions the radiation leads to the appearance of directed ratchet transport linked to an underlining strange attractor. The direction of transport can be efficiently changed by radiation polarization. The experimental realization of this effect in asymmetric antidot superlattices is discussed.
