Figure 5. Atomic concurrence as a function of dimensionless quantity ωt for different hopping rates ν in non-Markovian regime Γ = 0.2ω. (a) initial state ${\rho }_{{ABE}}^{(1)};$ (b) initial state ${\rho }_{{ABE}}^{(2)};$ (c) initial state ${\rho }_{{ABE}}^{(3)}$. The parameters are chosen as θ = π/6 and φ = π/6.
