Dynamical turbulent flow on the Galton board with friction - art. no. 034101

We study numerically and analytically the dynamics of charged particles on the Galton board, a regular lattice of disk scatters, in the presence of co nstant external force, magnetic field, and friction. It is shown that under certain conditions friction leads to the appearance of a strange chaotic a ttractor. In this regime the average velocity and direction of particle flo w can be effectively affected by electric and magnetic fields. We discuss t he applications of these results to the charge transport in antidot superla ttices and the stream of suspended particles in a viscous flow through scat ters.
