a, Hole–spin–spin correlation map. We show the bare correlator for diagonal and selected next-nearest spin bonds as a function of distance from the hole. The strongest signal is found in the sign change of the next-nearest-neighbour bond across the hole along x pointing towards a ___domain wall in the local AFM pattern. Along y, the correlations keep their expected positive sign from the AFM pattern. b, Similarly, by considering the string spin correlator (dark green) and normal spin–spin correlator (light green) at distance d = 2 (see text), we observe a change in sign, consistent with the change in parity of the AFM pattern. Shaded regions are theory results on Lx × Ly = 8 × 3 at kBT/tx = 0.3. Error bars are estimated using bootstrapping and are smaller than the marker size if not visible.
