Figure 3
Second-order correlation functions \({g_{i}^{(2)}(0)}\) (in the common logarithmic scale) versus the ratio of qubit-SMR coupling strength and the largest decay rate. Different predictions of the sub- and super-Poissonian boson number statistics, which can be interpreted, respectively, as the PB and PIT effects, of the photonic (a), phononic (b), and hybrid (c) modes assuming: (a) the SMR-driven system with parameters specified in Eq. (28) and (b) the QD-driven system with Eq. (29). All the shown Cases (i.e., 4, 6, 7, and 8) correspond to those listed in Table 1. The broken line at \(g=\max \kappa _j\) is the border line between the strong- and weak-coupling regimes.
