In our new paper, recently published in J. Phys. Chem. Lett., we use a detailed Lindblad master equation to model exciton dynamics in the light-harvesting antenna of purple bacteria, as well as a series of hypothetical antenna systems with randomly generated structures.
Astonishingly, it appears the beautiful, symmetric structures of natural antenna are not necessary to achieve highly efficient exciton transport.
