Figure 1From: Hierarchical-environment-assisted non-Markovian and its effect on thermodynamic propertiesSketch of the protocol of system S plus a hierarchical environment. S interacts with the environment: After \(A_{Q}\) interacts with \(\mathcal{R}_{n}\) (the nth ancilla of reservoir \(\mathcal{R}\)), it collides with S and is then directed to \(\mathcal{R}_{n+1}\)Back to article page
