Figure 1

(a) Illustration of a single sink potential located at one edge of a lattice system in equilibrium. (b) ED results of systems with L = 13 sites and N = 11 bosons. The critical values of Uc and Vc are determined from the fidelity metric by fixing V (square) and U (triangle), respectively. The dashed line shows the critical values from the mean field approximation, which agrees quantitatively with the ED results (symbols). (c) Fidelity metric and number of particles inside the sink for a system with L = 61 sites, particle number N = 20, and potential depth V = 38J simulated by the DMRG method.
