Fig. 1 (Color online) Photon number distribution $P_{s,a}$ for the state $\vert \xi \rangle _{s,a}$ in the Fock space ($n_{a},n_{b}$) for some different values of ($q,m,n,\varsigma$), where $(2,0,0,0.1),(4,0,0,0.1),(4,3,0,0.1),(4,0,3,0.1),(4,1,1,0.1),(4,1,1,0.6)$ respectively refer to (a), (b), (c), (d), (e), (f).
