Fig. 9: The evolution of (bi)polaron correlations as a function of hole concentration.

a–d Staggered polaron correlation function 〈χP(r)〉 and e–h staggered bipolaron correlation function 〈χBP(r)〉 at different doping levels. The red (gray) color indicates values larger (smaller) than zero. The numerical value of the correlation function, along with the associated 1σ statistical error are indicated at each point. All results are for a temperature \({(\beta {t}_{sp})}^{-1}=0.1\).
