Figure 3

Imbalance intensity $J_{\pm }^{(z)}(\tau )$ for the two-disks system. We have used some generic initial conditions such that $\left|S_{+}^{(1)}\right|{}^2=1.5$, $\left|S_{-}^{(1)}\right|{}^2=0.5$, $\left|S_{+}^{(2)}\right|{}^2=\left|S_{-}^{(2)}\right|{}^2=0$. Plot (a) is obtained with $\chi =2$ (self-trapping regime), while plot (b) corresponds to $\chi =1$ (Josephson oscillation regime). The solid and dashed lines correspond to $J_{\pm }^{(z)}$ components, respectively.Reuse & Permissions

Figure 4

Temporal behavior of the total intensity remaining inside the two disks when the first one is attached to a fiber. Panels (a) and (b) present the rescaled total intensity $\mathrm{P̃}(t)$ for initial excitation at the second disk and at the first disk, respectively. In (a) the leaking constant is $\gamma =0.7$ while in (b) we have used $\gamma =0.05$. In both cases, we have used various nonlinearity strengths above and below the critical nonlinearity parameter. (Respective curves are marked by different symbols as indicated in the plots).Reuse & Permissions

Figure 5

Decay rates extracted from the analysis of the rescaled total intensity shown in Figs. 4a and 4b. Plot (a) corresponds to initial excitation at the second disk. Plot (b) reports the initial decay rates when the excitation is prepared at the first disk. In both cases, we have used various nonlinearity strengths $\chi$ and leaking constants $\gamma$. The black lines represent the theoretical predictions Eq. (47), while various symbols correspond to different values of nonlinearity.Reuse & Permissions
