Figure 3From: Hierarchical-environment-assisted non-Markovian and its effect on thermodynamic propertiesChange of the NM with respect to p for fixed ϕ (\(\phi =0\)) (a), and the change of NM with respect to ϕ for fixed p (\(p=0.4\)) (b). For both plots \(T=\omega _{E}=1\), \(\gamma =\frac{\pi }{14}\) and \(\delta =\frac{\pi }{6}\) which is the Markovian region of coupling presented in Fig. 2Back to article page
