    • Absence of Quantum Oscillations and Dependence on Site Energies in Electronic Excitation Transfer in the Fenna–Matthews–Olson Trimer 

      Ritschel, Gerhard; Roden, Jan; Strunz, Walter T.; Aspuru-Guzik, Alán; Eisfeld, Alexander Jurgen (American Chemical Society, 2011)
      Energy transfer in the photosynthetic Fenna–Matthews–Olson (FMO) complex of green sulfur bacteria is studied numerically taking all three subunits (monomers) of the FMO trimer and the recently found eighth bacteriochlorophyll ...
    • Conformation of Self-Assembled Porphyrin Dimers in Liposome Vesicles by Phase-Modulation 2D Fluorescence Spectroscopy 

      Lott, Geoffrey A.; Perdomo-Ortiz, Alejandro; Utterback, James K.; Widom, Julia R.; Aspuru-Guzik, Alán; Marcus, Andrew H. (National Academy of Sciences, 2011)
      By applying a phase-modulation fluorescence approach to 2D electronic spectroscopy, we studied the conformation-dependent exciton coupling of a porphyrin dimer embedded in a phospholipid bilayer membrane. Our measurements ...
    • Environment-Assisted Quantum Transport 

      Rebentrost, Patrick; Mohseni, Masoud; Kassal, Ivan; Lloyd, Seth; Aspuru-Guzik, Alan (Institute of Physics, 2009)
      Transport phenomena at the nanoscale are of interest due to the presence of both quantum and classical behavior. In this work, we demonstrate that quantum transport efficiency can be enhanced by a dynamical interplay of ...
    • Finding Low-Energy Conformations of Lattice Protein Models by Quantum Annealing 

      Perdomo-Ortiz, Alejandro; Dickson, Neil; Drew-Brook, Marshall; Rose, Geordie; Aspuru-Guzik, Alan (Nature Publishing Group, 2012)
      Lattice protein folding models are a cornerstone of computational biophysics. Although these models are a coarse grained representation, they provide useful insight into the energy landscape of natural proteins. Finding ...
    • Probing Biological Light-Harvesting Phenomena by Optical Cavities 

      Caruso, Filippo; Saikin, Semion K.; Solano, Enrique; Huelga, Susana F.; Aspuru-Guzik, Alán; Plenio, Martin B. (American Physical Society, 2012)
      We propose a driven optical cavity quantum electrodynamics (QED) setup aimed at directly probing energy transport dynamics in photosynthetic biomolecules. We show that detailed information concerning energy transfer paths ...
