Real-time entanglement dynamics.
The contour plot of the entanglement EN(ρ+(t)) (in log scale) as a function of the time and the system-environment coupling strength η at zero initial environment temperature for sub-Ohmic spectral density. The other parameters are taken as ωc = 3ω0, κ = 0.5ω0 and r = 3.
