Average chiral current as a function of K / J for U / J = 11.02(5) Hz and J / h = 71(1) Hz, prepared using the plaquette coupling sequence. The solid line is a fit of the expected chiral current from a DMRG simulation with scaling factor A as a free parameter, yielding A = 0.57(3). The blue-shaded area denotes the 1 sigma confidence interval of the fit. The dashed trace shows the non-interacting current, scaled down to the same amplitude, and the vertical line denotes the critical point without interactions. The top panel indicates the many-body gap across the phase diagram. Each data point is averaged over 80 repetitions and 14 ladders with 48 sites.
