From: On the possibility of many-body localization in a doped Mott insulator
The binding of two holes at 
(L = 60 and Sz = 0) with increasing DMRG accuracy, i.e., increasing the number of states kept in DMRG from (a) to (c). Real-space distribution evolutions of spins 
and holes 
are shown here, where x denotes the lattice sites on one leg of the ladder (the values are the same at the two sites of each rung). From (a) to (c), the two holes are initially located far apart and each polarizes some spins nearby to form a Nagaoka polaron, which eventually bind together to form a localized two-hole bound state fully converged within the machine precision (see text).
