Fig. 5: Simulations of vibration-assisted energy transfer (VAET).

We set ϵ = 100 cm⁻¹ and Δ = 30 cm⁻¹. The x-axis represents the simulated time of the chemical model, determined by the chosen model parameters (see Section I of the Supplementary Material). a, b Time evolution of the donor-state population for coherent VAET models with κ = 30 cm⁻¹. Solid and dashed curves depict theoretical predictions of the ideal target and the noise-aware model, respectively. Circles represent experimental data and error bars are the standard deviation over 100 repetitions. In (a), bath temperature is fixed at 0 K (\(\bar{n}=0\)) and ν is varied. In (b), ν is fixed to the resonant value 104 cm⁻¹ and two temperatures 0 K and 300 K, which correspond to \(\bar{n}=0\) and 2.0, respectively, are simulated. c Time evolution of the donor-state population for dissipative VAET models with ν = 104 cm⁻¹ and Γ = 10cm⁻¹ at 0 K. Solid and dot-dashed curves depict theoretical predictions of the dephased spin-oscillator model and the damped spin-oscillator model, respectively. Circles denote experimental data. For κ = 0cm⁻¹, error bars indicate the standard deviation over 100 repetitions. For κ = 10 and 20 cm⁻¹, error bars indicate the standard deviation over 20 trials, each trial performed with a randomly drawn set of parameters and repeated 100 times.
