Extended Data Fig. 3: Multi-point Correlations at Different Global Chemical Potentials.
From: Directly imaging spin polarons in a kinetically frustrated Hubbard system
a, \({C}_{h}^{(3)}\) (red data) and \({C}_{d}^{(3)}\) (green data) evaluated at the bond closest to the dopant, and b, C(4) for two different datasets with distinct global chemical potentials. As these two datasets track each other well, particularly at low filling, we conclude spatial gradients do not appreciably suppress resonant tunneling to affect measured correlations. Filled data points have mean atom number 799(35) while empty data points have mean atom number 622(27).
