Entanglement dynamics of two quantum dots with initial sate |ϕ±(0)〉 for interdot distance (a) kd = π, (b) kd = π/2, (c) kd = π/8 and (d) kd = π/16. Here we assume symmetric coupling (μ1 = μ2 = μ) and Γk = Γ−k = γ1 = γ2 = γ. The solid red line represents γ = 0, and the dotted black line represents dynamics γ = μ/30. |
