Comparison of the results of the conditional propagation scheme and POP second-order master equation at the weak damping limit.
Comparison of the results of the MCMC and CD methods (the imaginary parts of the populations ρ11 and ρ22 in (a) and (b) are at the magnitude of 1.0 × 10−10).
We present four spectral densities: Ohmic spectral density with Lorentzian cutoff, Ohmic spectral density with exponential cutoff, and spectral densities with Gaussian cutoff with σ = γ and σ = 2γ (γ = 5 ps−1).
Kernels of four different spectral densities, Lorentzian (a), exponential cut (b), Gaussian with σ1 = γ (c), and Gaussian with σ2 = 2γ (d) (γ = 5 ps−1).
Population dynamics of FMO, ρ ii (t), in the site representation for the kernels of four different spectral densities: Lorentzian, exponential cutoff, and Gaussians with two different σ’s. (a) The results for Lorentzian, (b) the results for exponential cut, and (c) and (d) the results for Gaussians with two different widths, σ1 = γ and σ2 = 2γ (γ = 5 ps−1).
(a)–(d) Corresponding imaginary part (in reference to Fig. 5 ) of the populations, ρ ii (t) (y-axis scale is at the magnitude of 1.0 × 10−9 or 1.0 × 10−10 for (d)).
(a) The spectral densities with differential exponential cutoffs, ω c = 2, 5, 10 ps−1 and (b)–(d) the comparison of the results, the population dynamics of reduced systems, ρ ii , for the three different spectral densities.
