Figure 3: Temporal investigation of charge fractionalization.

(a) Δq(τ) at perfect dot to edge coupling D=1 for outer channel partitioning (orange points). Error bars on both the panels equal the standard error of the mean reflecting the statistical dispersion of points. (b) Δq(τ) at D=1 for the inner channel partitioning (black points). The orange and black lines on both the panels are simulations for Δq(τ). The vertical red lines correspond to a time delay matching the half-period of the excitation drive: τ=±T/2. Encircled c and d refer to the sketches on c and d. (c) Sketch of current pulses synchronization at τ=τ_s for inner channel partitioning. The outer channels are represented as orange lines, the inner as black lines. Negative (positive) charge pulses are represented by blue (red) colours. Pulses colliding synchronously are emphasized by red circles (electron/hole collision in this case). (d) Sketch of current pulses synchronization at τ=T/2−τ_s for inner channel partitioning. Pulses colliding synchronously are emphasized by red circles (electron/electron and hole/hole collisions in this case). exp., experimental; theo., theoretical.
