    • Exciton Coherence Lifetimes from Electronic Structure 

      Parkhill, John Anthony; Tempel, David Gabriel; Aspuru-Guzik, Alan (American Institute of Physics, 2012-04-06)
      We model the coherent energy transfer of an electronic excitation within covalently linked aromatic homodimers from first-principles. Our results shed light on whether commonly used models of the bath calculated via detailed ...
    • Exciton Transport in Thin-Film Cyanine Dye J-Aggregates 

      Valleau, Stephanie; Saikin, Semion K.; Yung, Man-Hong; Aspuru-Guzik, Alan (American Institute of Physics, 2012)
      We present a theoretical model for the study of exciton dynamics in J-aggregated monolayers of fluorescent dyes. The excitonic evolution is described by a Monte-Carlo wave function approach which allows for a unified ...
    • Gap-mode Plasmonic Nanocavity 

      Russell, Kasey Joe; Hu, Evelyn (American Institute of Physics, 2010)
      Here we describe the fabrication and characterization of a plasmonic nanocavity formed in the narrow gap between a Ag nanowire and a flat Ag substrate. The fluorescence spectrum of nanocrystals within the gap was strongly ...
    • Inexpensive Microscopy for Introductory Laboratory Courses 

      Peidle, Joseph D.; Stokes, Chris; Hart, Robert M; Franklin, Melissa; Newburgh, Ronald; Pahk, Joon; Rueckner, Wolfgang H. E.; Samuel, Aravinthan DT (American Association of Physics Teachers, 2009)
      We present an inexpensive apparatus for bright field and fluorescence microscopy with video capture, suitable for introductory laboratory courses. Experiments on Brownian motion and the Boltzmann distribution of suspended ...
    • Photoswitchable Fluorescent Probes for Localization-Based Super-Resolution Imaging 

      Dempsey, Graham Thomas (2013-02-21)
      In recent years, localization-based super-resolution imaging has been developed to overcome the diffraction limit of far-field fluorescence microscopy. Photoswitchable probes are a hallmark of this technique. Their ...
    • Time-Domain Fluorescence Diffuse Optical Tomography: Algorithms and Applications 

      Hou, Steven Shuyu (2014-10-21)
      Fluorescence diffuse optical tomography provides non-invasive, in vivo imaging of molecular targets in small animals. While standard fluorescence microscopy is limited to shallow depths and small fields of view, tomographic ...
