(Color online) Imaginary part of the matrix element ρ 21 ( 1 ) for the five-level system (red solid line) and two subsystems (black dashed-dotted line for FYTS and blue dashed line for TΛTS) as a function of the probe field detuning Δ p . (a) Ω c = 0.8γ21, (b) Ω c = 2.5γ21. The other parameters are as follows: Δ c = 0, Δ s = −Δ d = γ21, Ω d = Ω s = 2γ21, γ31 = γ41 = 100γ51 = 0.1γ21.
