Fractional Quantum Hall States of Atoms in Optical Lattices
(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
(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
(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
(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
(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
(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
(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
(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 ... -
Fracture of Heterogeneous Soft Materials
(2023-06-01)Soft materials are often heterogeneous, or composed of multiple parts. The heterogeneous structure of a soft material alters its behavior, and recent works have leveraged this fact to develop rubbers and hydrogels with ... -
Fracture of Highly Entangled Polymer Networks
(2022-06-06)Elastomers and gels are polymer networks, in which polymers entangle and crosslink. The topology of the polymer network significantly affects the material properties of elastomers and gels. The role of entanglements on ... -
Fragile Belonging: Motherhood and Migration in a Sanctuary City
(2022-06-06)A substantial body of research documents the gendered and racialized inequalities produced by U.S. immigration policies, inequalities that specifically cause harm to Latina immigrants as they strive for more secure futures ... -
The Fragmentary Muse and the Poetics of Refraction in Sappho, Sophocles, Offenbach
(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. ... -
Fragmented Labor Markets and the Spatial Structure of Cities in Developing Countries
(2015-06-26)This paper studies the impact of a fragmented labor market on city structure to explain the spatial coexistence of formal and informal labor sectors characteristic of cities in developing countries. I explore reasons for ... -

Fragonard: The Fantasy Figures
(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 ... -
The Frail Agony of Grace: Story, Act, and Sacrament in the Fiction of Cormac McCarthy
(2013-09-30)Although scholars have widely acknowledged the prevalence of religious reference in the work of Cormac McCarthy, no studies have yet paid any adequate attention to the most pervasive religious trope in all his works: the ... -
A framework for a teaching toolkit in entrepreneurship education
(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, ... -
A Framework for Incentivizing Deep Fixes
(AAAI, 2015)We study the problem of how to incentivize deep fixes to software bugs, where a deep fix attempts to correct the root cause of the bug instead of just suppressing it superficially. To this end we introduce a dynamic model ... -
A Framework for Inverse Scattering
(2016-08-26)Scattering materials are ubiquitous: from our skin and food, to every objects such as wax and soap, to industrial materials such as coatings and soft tissues. Common to all these materials is the complex way in which they ... -
A framework for modeling the detailed optical response of thick, multiple segment, large format sensors for precision astronomy applications
(SPIE, 2014)Near-future astronomical survey experiments, such as LSST, possess system requirements of unprecedented fidelity that span photometry, astrometry and shape transfer. Some of these requirements flow directly to the array ...
