The QSLT for the damped Jaynes-Cummings model as a function of the initial time parameter Ï„.
Here we choose the excited state as the initial state, vz = −1, vx = vy = 0. (a) the Markovian regime, γ0 = 0.1λ. (b) the non-Markovian regime, γ0 = 10λ. The red (dashed) line represents the decay of the excited population pτ. Parameters are chosen as, ω0 = 1, λ = 1 and τD = 1.
