DOI: 10.1016/j.chemphys.2019.110542
Abstract: Abstract Efficient quenching of (bacterio)chlorophyll triplet states by carotenoids prevents formation of reactive singlet oxygen in photosynthetic light-harvesting complexes. This protective process requires a close interaction between both types of pigments, which is usually ensured… read more here.

DOI: 10.1021/acs.jctc.2c01044
Abstract: We propose a machine learning (ML)-based strategy for an inexpensive calculation of excitonic properties of light-harvesting complexes (LHCs). The strategy uses classical molecular dynamics simulations of LHCs in their natural environment in combination with ML… read more here.

DOI: 10.1073/pnas.2210109119
Abstract: Significance The light-harvesting (LH) complexes of phototrophic bacteria absorb solar energy for photosynthesis, and it is important to understand how the protein components influence the way bound pigments absorb light. We studied the LH2 complexes… read more here.
