Probability density (A). This represents the probability density $\left|{\psi }_{\mathrm{s},n_1,n_2}\right(q_1,q_2,t){|}^2$ as a function of q₁ and t. Here, we did not take into account the squeezing effect (i.e., we let r₁=r₂=0). Various values we have taken are q₂=0, n₁=n₂=2, $\hslash =1$, R₀=R₁=R₂=0.1, L₀=L₁=L₂=1, C₁=1, C₂=1.2, p_1c(0) = p_2c(0) = 0, and δ = 0. The values of $\left(q_{1c}\right(0),q_{2c}(0),{\mathcal{E}}_0,\Omega )$ are (0,0,0,0) (a), (0.5,0.5,0,0) (b), (0.5,0.5,10,4) (c), and (0.5,0.5,0.5,0.53) (d). All values are taken dimensionlessly for convenience: this convention will be used in all subsequent figures.
