Top: Time evolution of (a) electronic wave packet, (b) excited-state vibrational wave packet and (c) ground-state vibrational wave packet. In (a,c), blue lines are for our model in non-adiabtic regime; In (b) the blue and red lines correspond to excited-state vibrational wave packets 〈A, 0|ρ|A, 1〉 and 〈B, 0|ρ|B, 1〉, respectively. Bottom: Time evolution of the excitonic coherence in delocalized basis, where blue lines correspond to non-adiabatic regime. Purple lines in (a,b,c) electronic and (d,e,f) excitonic coherences are for adiabatic regime, respectively. The parameters are: Frank-Condon factor 
, Δ = 0.023εA, electronic coupling J = 0.01εA, frequency of vibrational mode ħω = 1.33Δ, kBT1 = 0.63εA, kBT2 = 1.4Δ, Debye frequency ħωd = 0.7Δ, typical decay rate hγ = 0.0005εA, reorganization energy ER = 0.23Δ and t0 = 10γ−1.
