    • 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 ...
    • Exciton-Phonon Information Flow in the Energy Transfer Process of Photosynthetic Complexes 

      Rebentrost, Frank Patrick; Aspuru-Guzik, Alan (2010-12-15)
      Non-Markovian and non-equilibrium phonon effects are believed to be key ingredients in the energy transfer in photosynthetic complexes, especially in complexes which exhibit a regime of intermediate exciton-phonon coupling. ...
    • Exciton-Related Electroluminescence from ZnO Nanowire Light-Emitting Diodes 

      Zimmler, Mariano; Voss, Tobias; Ronning, Carsten; Capasso, Federico (American Institute of Physics, 2009)
      The authors study the microscopic origin of the electroluminescence from zinc oxide (ZnO) nanowire light-emitting diodes (LEDs) fabricated on a heavily doped p-type silicon (p-Si) substrate. By comparing the low-temperature ...
    • Excitons in a reconstructed moiré potential in twisted WSe2/WSe2 homobilayers 

      Andersen, Trond; Scuri, Giovanni; Sushko, Andrey; De Greve, Kristiaan; Sung, Jiho; Zhou, You; Wild, Dominik S.; Gelly, Ryan J.; Heo, Hoseok; Berube, Damien; Joe, Andrew Y.; Jauregui, Luis A.; Watanabe, Kenji; Taniguchi, Takashi; Kim, Philip; Park, Hongkun; Lukin, Mikhail D. (Springer Science and Business Media LLC, 2021-01-04)
      Moiré superlattices in twisted van der Waals (vdW) materials have recently emerged as a promising platform for engineering electronic and optical properties. A major obstacle to fully understanding these systems and ...
    • Excitons in incompressible quantum liquids 

      Rashba, Emmanuel (Walter de Gruyter GmbH, 1995)
      A theory of excitons in semiconductors in the Fractional Quantum Hall (FQH) Effect regime is presented. Non-conventional properties of magnetoexcitons in this regime originate from the fact that elementary excitations of ...
    • Excitons: how we worked on the Volume 

      Rashba, Emmanuel (Elsevier BV, 2000)
    • Exclusivist Republicanism and the Non-Monarchical Republic 

      Hankins, James (SAGE Publications, 2010)
      The idea that a republic is the only legitimate form of government and that non-elective monarchy and hereditary political privileges are by definition illegitimate is an artifact of late eighteenth century republicanism, ...
    • The Excremental Poetics of Daniel Pennac’s Journal D’un Corps 

      Kim, Annabel (Oxford University Press (OUP), 2019-04-21)
      The French literary landscape, from its earliest stages, is littered with faecal matter. Medieval fabliaux such as Audigier give us a coprophilic knight, the eponymous Audigier, who falls in love with women in proportion ...
    • Executive Compensation: A Modern Primer 

      Edmans, Alex; Gabaix, Xavier (American Economic Association, 2016)
      This article studies traditional and modern theories of executive compensation, bringing them together under a simple unifying framework accessible to the general-interest reader. We analyze assignment models of the level ...
    • Executive Function, Visual Attention and the Cocktail Party Problem in Musicians and Non-Musicians 

      Clayton, Kameron K.; Swaminathan, Jayaganesh; Yazdanbakhsh, Arash; Zuk, Jennifer; Patel, Aniruddh D.; Kidd, Gerald (Public Library of Science, 2016)
      The goal of this study was to investigate how cognitive factors influence performance in a multi-talker, “cocktail-party” like environment in musicians and non-musicians. This was achieved by relating performance in a ...
    • Exercise-Induced Bone Formation Is Poorly Linked to Local Strain Magnitude in the Sheep Tibia 

      Wallace, Ian J.; Demes, Brigitte; Mongle, Carrie; Pearson, Osbjorn M.; Polk, John D.; Lieberman, Daniel E. (Public Library of Science, 2014)
      Functional interpretations of limb bone structure frequently assume that diaphyses adjust their shape by adding bone primarily across the plane in which they are habitually loaded in order to minimize loading-induced ...
    • Exhausted Oats ([Verg.] Dirae 15)? 

      Thomas, Richard F. (The Johns Hopkins University Press, 1988)
    • EXIST ’s Gamma‐Ray Burst Sensitivity 

      Band, D. L.; Grindlay, J. E.; Hong, J.; Fishman, G.; Hartmann, D. H.; Garson, A. III; Krawczynski, H.; Barthelmy, S.; Gehrels, N.; Skinner, G. (American Astronomical Society, 2008)
    • Existence of Equilibrium in Large Double Auctions 

      Fudenberg, Drew; Mobius, Markus; Szeidl, Adam (Elsevier, 2007)
      We show the existence of a pure strategy, symmetric, increasing equilibrium in dou- ble auction markets with correlated, conditionally independent private values and many participants. The equilibrium we find is arbitrarily ...
    • Exit Options in Corporate Finance: Liquidity versus Incentives 

      Aghion, Philippe; Bolton, P.; Tirole, J. (Oxford University Press (OUP), 2004)
      This paper provides a first study of the optimal design of active monitors' exit options in a problem involving a demand for liquidity and costly monitoring of the issuer. Optimal incentives to monitor the issuer may involve ...
    • Exit the Frog, Enter the Human: Physiology and Experimental Psychology in Nineteenth-Century Astronomy 

      Canales, Jimena (Cambridge University Press, 2001)
      This paper deals with one of the first attempts to measure simple reactions in humans. The Swiss astronomer Adolph Hirsch investigated personal differences in the speed of sensory transmission in order to achieve accuracy ...
