    • Atomistic Study of Energy Funneling in the Light-Harvesting Complex of Green Sulfur Bacteria 

      Huh, Joonsuk; Saikin, Semion K.; Brookes, Jennifer Clare; Valleau, Stephanie; Fujita, Takatoshi; Aspuru-Guzik, Alan (American Chemical Society (ACS), 2014)
      Phototrophic organisms such as plants, photosynthetic bacteria, and algae use microscopic complexes of pigment molecules to absorb sunlight. Within the light-harvesting complexes, which frequently have several functional ...
    • Boson sampling for molecular vibronic spectra 

      Huh, Joonsuk; Guerreschi, Gian Giacomo; Peropadre, Borja; McClean, Jarrod R.; Aspuru-Guzik, Alan (Nature Publishing Group, 2015)
      Controllable quantum devices open novel directions to both quantum computation and quantum simulation. Recently, a problem known as boson sampling has been shown to provide a pathway for solving a computationally intractable ...
    • Chromatic acclimation and population dynamics of green sulfur bacteria grown with spectrally tailored light 

      Saikin, Semion K.; Khin, Yadana; Huh, Joonsuk; Hannout, Moataz; Wang, Yaya; Zare, Farrokh; Aspuru-Guzik, Alán; Tang, Joseph Kuo-Hsiang (Nature Publishing Group, 2014)
      Living organisms have to adjust to their surrounding in order to survive in stressful conditions. We study this mechanism in one of most primitive creatures – photosynthetic green sulfur bacteria. These bacteria absorb ...
    • Linear-Algebraic Bath Transformation for Simulating Complex Open Quantum Systems 

      Huh, Joonsuk; Mostame, Sarah; Fujita, Takatoshi; Yung, Man-Hong; Aspuru-Guzik, Alan (IOP Publishing, 2014)
      In studying open quantum systems, the environment is often approximated as a collection of non-interacting harmonic oscillators, a configuration also known as the star-bath model. It is also well known that the star-bath ...
    • A stochastic reorganizational bath model for electronic energy transfer 

      Fujita, Takatoshi; Huh, Joonsuk; Aspuru-Guzik, Alan (AIP Publishing, 2014)
      Environmentally induced fluctuations of the optical gap play a crucial role in electronic energy transfer dynamics. One of the simplest approaches to incorporate such fluctuations in energy transfer dynamics is the well ...
    • Temperature and Carbon Assimilation Regulate the Chlorosome Biogenesis in Green Sulfur Bacteria 

      Tang, Joseph Kuo-Hsiang; Saikin, Semion K.; Pingali, Sai Venkatesh; Enriquez, Miriam M.; Huh, Joonsuk; Frank, Harry A.; Urban, Volker S.; Aspuru-Guzik, Alan (Elsevier BV, 2013)
      Green photosynthetic bacteria adjust the structure and functionality of the chlorosome—the light-absorbing antenna complex—in response to environmental stress factors. The chlorosome is a natural self-assembled aggregate ...
    • Theoretical characterization of excitation energy transfer in chlorosome light-harvesting antennae from green sulfur bacteria 

      Fujita, Takatoshi; Huh, Joonsuk; Saikin, Semion K.; Brookes, Jennifer Clare; Aspuru-Guzik, Alan (Springer Science + Business Media, 2014)
      We present a theoretical study of excitation dynamics in the chlorosome antenna complex of green photosynthetic bacteria based on a recently proposed model for the molecular assembly. Our model for the excitation energy ...
