The QSL time τQSL (a), the non-Markovianity (b-solid line) and the quantity (b-dashed line) associated the non-Markovianity and decoherence factor as a function of the ohmicity parameter s for the nonequilibrium environment. Other parameters are the same as those in Fig. 1 and the actual driving time τ = 5.
