Polariton quantum blockade in a photonic dot. A. Verger, C. Ciuti and I. Carusotto in Phys. Rev. B 73:193306 (2006). What the paper says!?
This overlay of their famed Fig. 1 compares their numerical result to our analytical solution[1] at vanishing pumping (more correlated):
Their result is probably correct despite the variation, and due to their use of a finite pumping, which dampens the correlations.
