The transmission coefficient T (blue solid line), reflection coefficient R (red dashed line), and their summation T + R (yellow dash-dot line) as a function of energy detuning (E_k – ω_c), (b) The real (blue solid line) and imaginary (red dash line) parts of the effective potential energy at Ω = ω_c = 10, J = 10, λ = 20, and γ = 4. The vertical black line shows E_k = 0 and ω = 0 respectively.
