The timescales of population dynamics associated with the energy funnel were determined with pump-probe measurements with laser spectra centered at different wavelengths, so that different sets of pigments could be initially excited. From the pump-probe results analysis combined with quantum chemical calculations, the model of energy transfer depicted in panel (c) of Fig. 5 can be proposed. 

The nature of energy transport and percolation has been examined in mixed molecular crystals which are regarded as fractal structures S0. Strong guest host interaction produces induced energy funnels which are found to mask the fractal nature of the... 

However, each of these states plays a role in gathering light. The operation of the light-harvesting antenna of purple bacteria is based on an energy funnel to focus excitation energy to the reaction center. There are two obvious ways to construct such a funnel (1) Select different chemical species that absorb at the...
