Energy transfer dynamics in an RC–LH1–PufX tubular photosynthetic membrane

Exciton–vibrational coupling in the dynamics and spectroscopy of Frenkel excitons in molecular aggregates

“…This paper triggered a host of further improvements such as extensions to include multiple spectral densities [210,211] or some filtering [212] or pre-screening [213] for optimizing performance. Among the various applications those directed to exciton dynamics [146,[214][215][216][217] and in particular to photosynthetic light-harvesting [218][219][220][221][222][223][224][225][226][227][228][229][230][231] take a prominent place.…”

The Light-Harvesting Apparatus in Purple Photosynthetic Bacteria: Introduction to a Quantum Biological Device

“…A similar calculation can be performed for the transfer rate between LH1-RC complexes 13,14,59 and between LH2 and LH1-RC complexes. 13,14 These rates can be employed to construct a model for exciton migration across the whole chromatophore.…”

“…47 The correct inclusion of thermal disorder and quantum mechanics in the theoretical models of light-harvesting processes has been the topic of many studies. 7,[48][49][50][51][52][53][54][55][56][57][58][59][60] The laws of quantum physics constraining light-harvesting processes appear to have been wonderfully exploited by the evolution of photosynthetic systems. 14,61 The combination of protein structural data with physics-based computational models can accurately portray the light-harvesting function of a photosynthetic protein complex as shown below.…”

Proposal for verifying dipole properties of light-harvesting antennas

“…Some species, such as R. sphaeroides, have a polypeptide component termed "W" is found at the opening, similar to the PufX polypeptide in several Rba. species for which a precise function has long been debated [17,18,14,19,20]. The elliptical LH1 complex has an outer long axis of length 110Å and a short axis of length 95Å ; the greatest dimension of the inside of this LH1 is 78Å.…”
