Figure 4

(a) Illustration of dynamically emerged source-sink combination. The potential well for the source is on the left most site while the sink appears on the right most site. In (b–f) we show the results with system size L = 13 and N = 12 particles. (b–d) Density distribution for two selected times, t = 0 (blue circle) and t = 6t0 (red square). The inset shows the density contour versus time with interaction strength U = J and potential depth (b) V = 2J, (c) V = 6J, and (d) V = 36J. (e) Number of bosons on the source site versus time with U = J. (f) Particle number difference at the source site between the initial and later (t = 10t0) times versus V. Averse response manifests itself in (e and f) as larger depth drives less particles across the system.
