Figure presents contour plots for the change of the BLP metric through time for the first 200 ADOs, for the ODR and the UDR cases. The vertical red lines depict which auxiliaries are terminators. In the UDR regime there are very few terminators in the first 200 ADOs, with each terminator representing the end of a different Matsubara axis. Additionally, there is structure in the BLP for early ADOs with each Matsubara axis contributing to recurrence to the system from the bath. Within these regions the BLP is lowest in the first few hundred femtoseconds for the lowest ADO numbers. This corre- sponds to recurrence of virtual information feeding back towards the density matrix most rapidly for lower ADOs and tiers. This is consistent with the fact that higher tiers correspond to thermal Markovian behaviours. Additionally, UDR relative to IDR lacks the well defined recurrence structure at early times. This clearly correlates with the fact that recurrence of information occurs much more readily in underdamped cases, compared to overdamped scenarios.
