Figure 2: Ping–pause–pong experiments.
(a) Illustrations of the ping, pause and pong steps of our experiment. (b) A typical current trace from a ping–pause–pong experiment, showing the ping and pong translocation signatures, and illustrating tp and tr. The current transients near 0.02 and 5.39 s were caused by sudden changes in V. The wavy lines indicate breaks in the current axis. Slow drift of the current baseline caused the jump in current observed at the break in the time axis in the pause phase.
