Fig. 3: Photosynthetic energy transport using the Δβ photonic model.
From: Simulating photosynthetic energy transport on a photonic network
a The spectral density formed by the coloured noise introduced on Waveguide 3 is shown in the blue shadow. The red bars show the power spectral density for BChl 3 in a pigments of the monomeric subunits of the FMO protein via normal mode analysis from Ref. 30. Inset shows a spectral density generated from the white noise. b Reorganisation energy versus noise variance at Site 7. The sampling frequency and period are fs = 1 mm−1 and tc = 20 mm, respectively. The variance \({\sigma }^{2}(\Delta {\beta }_{7})=\langle {(\Delta {\beta }_{7})}^{2}\rangle -{\langle \Delta {\beta }_{7}\rangle }^{2}\) dependents on Δβ7 amplitude ΔβA,7. The parameters of the linear fitting are given in the bottom right of the figure. c The transport efficiency at an early transport length with (red) and without (blue) vibrational assistance. ΔβA for all waveguides are set to be 0.5 mm−1.
