Directing transport by polarized radiation in presence of chaos and dissipation

TL;DR

This paper demonstrates how polarized monochromatic radiation can induce and control directed particle transport in a chaotic system with dissipation, with potential experimental applications in asymmetric superlattices.

Contribution

It introduces a numerical study showing radiation-induced directed transport linked to strange attractors and demonstrates control of transport direction via polarization.

Findings

Radiation induces directed transport in a chaotic particle system.

Transport direction can be controlled by radiation polarization.

The effect is potentially realizable in asymmetric antidot superlattices.

Abstract

We study numerically the dynamics of particles on the Galton board of semi-disk scatters in presence of monochromatic radiation and dissipation. It is shown that under certain conditions the radiation leads to appearance of directed 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.
