Schematic diagram of the sample cell of the ABEL trap. (a) Top view. (b) Side view (not to scale).
(Color online) Trapping of a particle. (a) Average of 30 video frames showing a single trapped particle. The trapping electrodes are visible protruding from the edges of the image. (b) Comparison of trajectories of a diameter particle with the trap on and with the trap off. Inset: histogram of displacements from equilibrium.
Trajectory of a particle over the course of , as it was manipulated to draw out a smiley face. The trajectory was specified by a file containing 1800 target positions, updated at . (Two of the 1800 data points—those joining the eyes and mouth—are not plotted.)
