Entanglement dynamics of two quantum dots with initial sate |ψ−(0)〉 for interdot distance (a) kd = π, (b) kd = 3π/4, (c) kd = π/2, and (d) kd = π/4. 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 at γ = μ/30. |
