Accessible information J SE ( t ) (blue line), the entanglement of formation E SA ( t ) (red line), for (a) η = 0, (b) η = 1, (c) η = 3, respectively, with Δ = 0, and in the insets, the decay rate γ ( t ) / γ 0 (orange line) as a function of the dimensionless quantity γ 0 t , in the Markovian regime where λ / γ 0 = 3 . Here, panel (a) shows the monotonicity of information flow in the absence of DDIs, while panels (b) and (c) show non-monotonic behavior, revealing how the dynamics change when DDIs are introduced in the Markovian regime.
