    • Environment-Assisted Quantum Walks in Photosynthetic Energy Transfer 

      Mohseni, Masoud; Rebentrost, Patrick; Lloyd, Seth; Aspuru-Guzik, Alan (American Institute of Physics, 2008)
      Energy transfer within photosynthetic systems can display quantum effects such as delocalized excitonic transport. Recently, direct evidence of long-lived coherence has been experimentally demonstrated for the dynamics of ...

    • Hidden Stochastic Nature of a Single Bacterial Motor 

      Korobkova, Ekaterina A.; Emonet, Thierry; Park, Heungwon; Cluzel, Philippe (American Physical Society, 2006)
      The rotary flagellar motor of Escherichia coli bacterium switches stochastically between the clockwise (CW) and counterclockwise (CCW) direction. We found that the CW and CCW intervals could be described by a gamma ...

    • Multipartite Quantum Entanglement Evolution in Photosynthetic Complexes 

      Zhu, Jing; Kais, Sabre; Aspuru-Guzik, Alan; Rodriques, Sam; Brock, Ben; Love, Peter J. (American Institute of Physics, 2012)
      We investigate the evolution of entanglement in the Fenna-Matthew-Olson (FMO) complex based on simulations using the scaled hierarchy equation of motion (HEOM) approach. We examine the role of multipartite entanglement in ...

    • Non-Markovian Quantum Jumps in Excitonic Energy Transfer 

      Rebentrost, Patrick; Chakraborty, Rupak; Aspuru-Guzik, Alán (American Institute of Physics, 2009)
      We utilize the novel non-Markovian quantum jump (NMQJ) approach to stochastically simulate exciton dynamics derived from a time-convolutionless master equation. For relevant parameters and time scales, the time-dependent, ...
