      Idema, Wilt Lukas (Maney Publishing, 2012)
    • Foxp3 Interacts With c-Rel to Mediate NF-\(\kappa\)B Repression 

      Loizou, Louiza; Andersen, Kristian G; Betz, Alexander G. (Public Library of Science, 2011)
      Expression of the lineage-specific DNA-binding factor Foxp3 controls the development and function of naturally occurring regulatory T cells. Foxp3 has been shown to interact with a multitude of transcriptional regulators ...
    • FOXP3+ T Cells Recruited to Sites of Sterile Skeletal Muscle Injury Regulate the Fate of Satellite Cells and Guide Effective Tissue Regeneration

      Muscle injury induces a classical inflammatory response in which cells of the innate immune system rapidly invade the tissue. Macrophages are prominently involved in this response and required for proper healing, as they ...
    • Förster Coupling in Nanoparticle Excitonic Circuits 

      Rebentrost, Patrick; Stopa, Michael; Aspuru-Guzik, Alán (American Chemical Society, 2010)
      Exciton transport in semiconductor nanoparticles underlies recent experiments on electrically controlled nanostructures and proposals for new artificial light-harvesting systems. In this work, we develop a novel method for ...
    • Fractional and integer quantum Hall effects in the zeroth Landau level in graphene 

      Abanin, Dmitry A.; Feldman, Benjamin E.; Yacoby, Amir; Halperin, Bertrand I. (American Physical Society, 2013)
      Experiments on the fractional quantized Hall effect in the zeroth Landau level of graphene have revealed some striking differences between filling factors in the ranges 0 < vertical bar nu vertical bar < 1 and 1 < ...
    • Fractional Chern Insulators in Magic-Angle Twisted Bilayer Graphene 

      Xie, Yonglong; Pierce, Andrew; Park, Jeong Min; Parker, Daniel E.; Khalaf, Eslam; Ledwith, Patrick; Cao, Yuan; Lee, Seung Hwan; Chen, Shaowen; Forrester, Patrick R.; Watanabe, Kenji; Taniguchi, Takashi; Vishwanath, Ashvin; Jarillo-Herrero, Pablo; Yacoby, Amir (Springer Science and Business Media LLC, 2021-12-15)
      <jats:title>Abstract</jats:title><jats:p>Fractional Chern insulators (FCIs) are lattice analogues of fractional quantum Hall states that may provide a new avenue towards manipulating non-Abelian excitations. Early theoretical ...
    • Fractional quantum Hall effect in optical lattices 

      Hafezi, M.; Sørensen, A. S.; Demler, Eugene A.; Lukin, Mikhail D. (American Physical Society (APS), 2007)
      We analyze a recently proposed method to create fractional quantum Hall FQH states of atoms confined in optical lattices A. Sørensen et al., Phys. Rev. Lett. 94, 086803 2005 . Extending the previous work, we investigate ...
    • Fractional Quantum Hall Phase Transitions and Four-Flux States in Graphene 

      Feldman, Benjamin Ezekiel; Levin, Andrei Joseph; Krauss, Benjamin; Abanin, Dmitry; Halperin, Bertrand I.; Smet, Jurgen H.; Yacoby, Amir (American Physical Society (APS), 2013)
      Graphene and its multilayers have attracted considerable interest because their fourfold spin and valley degeneracy enables a rich variety of broken-symmetry states arising from electron-electron interactions, and raises ...
    • Fractional Quantum Hall States of Atoms in Optical Lattices 

      Sørensen, Anders S.; Demler, Eugene A.; Lukin, Mikhail D. (American Physical Society (APS), 2005)
      We describe a method to create fractional quantum Hall states of atoms confined in optical lattices. We show that the dynamics of the atoms in the lattice is analogous to the motion of a charged particle in a magnetic field ...
    • Fractionalization 

      Alesina, Alberto; Devleeschauwer, Arnaud; Easterly, William; Kurlat, Sergio; Wacziarg, Romain (Springer Verlag, 2003)
      We provide new measures of ethnic, linguistic, and religious fractionalization for about 190 countries. These measures are more comprehensive than those previously used in the economics literature and we compare our new ...
    • Fractionalization patterns in strongly correlated electron systems: Spin-charge separation and beyond 

      Demler, Eugene A.; Nayak, Chetan; Kee, Hae-Young; Kim, Yong Baek; Senthil, T. (American Physical Society (APS), 2002)
      We discuss possible patterns of electron fractionalization in strongly interacting electron systems. A popular possibility is one in which the charge of the electron has been liberated from its Fermi statistics. Such a ...
    • Fractionalized Fermi liquid on the surface of a topological Kondo insulator 

      Thomson, Alexandra Rose; Sachdev, Subir (American Physical Society (APS), 2016)
      We argue that topological Kondo insulators can also have 'intrinsic' topological order associated with fractionalized excitations on their surfaces. The hydridization between the local moments and conduction electrons can ...
    • Fractionalized Fermi liquid with bosonic chargons as a candidate for the pseudogap metal 

      Chatterjee, Shubhayu; Sachdev, Subir (American Physical Society (APS), 2016)
      Doping a Mott-insulating Z 2 spin liquid can lead to a fractionalized Fermi liquid (FL*). Such a phase has several favorable features that make it a candidate for the pseudogap metal for the underdoped cuprates. We focus ...
    • Fractionating Polymer Microspheres as Highly Accurate Density Standards 

      Bloxham, William Henry; Hennek, Jonathan; Kumar, Ashok Ashwin; Whitesides, George McClelland (American Chemical Society (ACS), 2015)
      This paper describes a method of isolating small, highly accurate density-standard beads and characterizing their densities using accurate and experimentally traceable techniques. Density standards have a variety of ...
    • Fractionation of multiple sulfur isotopes during phototrophic oxidation of sulfide and elemental sulfur by a green sulfur bacterium 

      Zerkle, Aubrey L.; Farquhar, James; Johnston, David T; Cox, Raymond P.; Canfield, Donald E. (Elsevier BV, 2009)
      We present multiple sulfur isotope measurements of sulfur compounds associated with the oxidation of H2S and S0 by the anoxygenic phototrophic S-oxidizing bacterium Chlorobium tepidum . Discrimination between 34S and 32S ...
    • Fracture of electrodes in lithium-ion batteries caused by fast charging 

      Zhao, Kejie; Pharr, Matt; Vlassak, Joost J.; Suo, Zhigang (AIP Publishing, 2010)
      During charging or discharging of a lithium-ion battery, lithium is extracted from one electrode and inserted into the other. This extraction-insertion reaction causes the electrodes to deform. An electrode is often composed ...
    • The Fragmentary Muse and the Poetics of Refraction in Sappho, Sophocles, Offenbach 

      Nagy, Gregory (transcript Verlag, 2009)
      The idea of a fragmentary Muse comes from a fragmentary opera, The Tales of Hoffmann (Les Contes d’Hoffmann), by Jacques Offenbach. Such a Muse, I argue, embodies a complex metaphor that I sum up in one word, refraction. ...
    • Fragonard: The Fantasy Figures 

      Lajer-Burcharth, Ewa (Artforum International Magazine, 2017-12)
      RARELY DOES A MERE SHEET OF PAPER radically challenge our view of a major artist’s oeuvre. But this is exactly what happened when, in June 2012, a previously unknown page of brown-ink-and-pencil sketches by Jean-Honoré ...
    • A framework for a teaching toolkit in entrepreneurship education 

      Fellnhofer, Katharina (Inderscience Publishers, 2017)
      Despite mounting interest in entrepreneurship education (EE), innovative approaches such as multimedia, web-based toolkits including entrepreneurial storytelling have been largely ignored in the EE discipline. Therefore, ...
