Figure 2

Sudden emergence of a sink at (a) the left edge and (e) the center of the system with size L = 13 and N = 11 bosons. The top and bottom rows show the results correspond to the setups of (a) and (e), respectively. (b) and (f) Time evolution of particle number in the sink potential. The insets show the corresponding current flow into the sink. (c) and (d) (g,h) Overall density evolution with V = 3J and U = 0 (c and g) and with V = 3J and U = 2J (d) and (h). The upper (lower) color bars are for (c) and (d) (g,h). (i) Short time behavior of particle number in the dynamical sink potential versus potential depth under different interaction strength. (j) The same plot as (i) with the sink located at the center of the system.
