Abstract

The electrostatic charging of insulators is notoriously irreproducible. Using experiments and simulations we study the charging of a single bouncing ball on a vibrating surface. We show that a ball's final charge results from a coupling between its chaotic dynamics and its evolving charge distribution. This results in a permanent charge dipole which traps the particle in an "orientational absorbing state" preventing further charging. The variability of each particle's final charge is a direct consequence of this dynamical coupling.
