The effects of reduction of ω0.
(a) The concurrence obtained from the TC2 method (dot-dashed), HEOM (dashed) and TL2 (solid), for ω0 = 40 cm−1. The reduction of ω0 leads to a manifest concurrence revival around 100 fs. The concurrence obtained from HEOM is still monotonically decreasing. The other parameters are: λ = 5 cm−1, γ = 50 cm−1 and T = 200 K. (b) The corresponding non-Markovianity versus temperature. The result of TC2 shows finite non-Markovianity, while that from TL2 shows very small non-Markovianity and only at low temperatures. The result from HEOM is Markovian due to its monotonically-decreasing concurrence.
