From: On the possibility of many-body localization in a doped Mott insulator
(a) A converged two-hole bound state localized in a different place on the ladder as compared to Fig. 4(c), with S = 7 and Sz = 7; (b) The collapsing of the localized bound pair profile at a smaller β (=1/4); (c) The two holes are always unpaired and remain mobile after turning off the phase string (cf. Sec. II E). The two-leg ladder length L = 60.
