(Color online) Amplitude ∣ ε ˜ ( t ) ∣ versus Γ t with delay Γ τ 1 = 0.1 (a) and Γ τ 1 = 1 (b) in the following cases: no termination (black solid line), phase φ 1 = 2 n π + π / 2 (blue dotted line), φ 1 = 2 n π + π (red dashed line), φ 1 = 2 n π (green dash-dotted line). We have set the following parameters: a = 2 b , ω A = ( Ω 31 + Ω 51 ) / 2 .
