Table 1 Different predictions of the super- and sub-Poissonian particle (i.e., photon, phonon or hybrid photon–phonon)-number statistics (PNS) corresponding, respectively, to PIT and PB, for the photon mode a, phonon mode b, and hybrid photon–phonon mode c, where \(f_{abc}=\left( \mathrm{sgn}[g_a^{(2)}(0)-1],\mathrm{sgn}[g_b^{(2)}(0)-1],\mathrm{sgn}[g_c^{(2)}(0)-1]\right)\) and the last column indicates each prediction of the mode a, b, and c in the specific colour that is used in our plots.
