[Aspuru-Guzik group list] Group meeting tomorrow: Takatoshi

Hi Everyone, Please join us tomorrow at 2pm in the Division room for group meeting. This week, Takatoshi will be presenting "Exciton dynamics in chlorosomes". An abstract is provided below. Abstract: Chlorosomes are the largest and most efficient natural light-harvesting systems. They are composed of large numbers of bacteriochlorophylls organized into supramolecular aggregates. In this talk, I will present a theoretical study on the exciton dynamics in the chlorosomes. I will show that the exciton diffusion in the chlorosomes is highly anisotropic, which may be relevant to efficient transfer of excitation energy to a reaction center. Through a comparison among different theoretical models, the memory effects associated to the environmental fluctuations are found to enhance the exciton diffusion. -- Ryan Babbush | PhD Student in Chemistry (949) 331-3943 | babbush(a)fas.harvard.edu Harvard University | Aspuru-Guzik Research Group 12 Oxford Street, Box 400 | Cambridge, MA 02138
