Figure 4: Modification of LHC energy relaxation pathways.
From: Strong coupling between chlorosomes of photosynthetic bacteria and a confined optical cavity mode

Energy level diagram of a green sulfur bacteria LHC coupled to an optical cavity. The red arrows show the energy transport pathway in an unperturbed LHC. Strong interaction of the cavity photons with the chlorosome exciton states result in formation of polariton branches with the Rabi splitting about 150 meV. The green arrows show possible energy pathways in the coupled system.
