  • Breznay, Nicholas P.; Michaeli, Karen; Tikhonov, Konstantin S.; Finkelstein, Alexander M.; Tendulkar, Mihir; Kapitulnik, Aharon (American Physical Society, 2012-07)
    We have studied the Hall effect in superconducting tantalum nitride films. We find a large contribution to the Hall conductivity near the superconducting transition, which we can track to temperatures well above T[subscript ...
  • Song, Justin Chien Wen; Levitov, Leonid (American Physical Society, 2013-09)
    Massless Dirac fermions in graphene at charge neutrality form a strongly interacting system in which both charged and neutral (energy) modes play an important role. These modes are essentially decoupled in the absence of ...
  • Michaeli, Karen; Tikhonov, Konstantin S.; Finkel’stein, Alexander M. (American Physical Society, 2012-07)
    Near the superconducting phase transition, fluctuations significantly modify the electronic transport properties. Here we study the fluctuation corrections to the Hall conductivity in disordered films, extending previous ...
  • Lee, Yun Seog; Winkler, Mark Thomas; Siah, Sin Cheng; Brandt, Riley E.; Buonassisi, Tonio (American Institute of Physics (AIP), 2011-05)
    Cuprous oxide (Cu[subscript 2]O) is a promising earth-abundant semiconductor for photovoltaic applications. We report Hall mobilities of polycrystalline Cu[subscript 2]O thin films deposited by reactive dc magnetron ...
  • Liu, Hong; Ooguri, Hirosi; Stoica, Bogdan (American Physical Society, 2014-10)
    We use the holographic approach to compare the Hall viscosity η[subscript H] and the angular momentum density J in gapless systems in 2 + 1 dimensions at finite temperature. We start with a conformal fixed point and turn ...
  • Cappellaro, Paola; Ticozzi, Francesco; Lucchese, Riccardo; Viola, Lorenza (Institute of Electrical and Electronics Engineers (IEEE), 2012-08)
    We consider finite-dimensional Markovian open quantum systems, and characterize the extent to which time-independent Hamiltonian control may allow to stabilize a target quantum state or subspace and optimize the resulting ...
  • Bookatz, Adam D.; Wocjan, Pawel; Viola, Lorenza (Institute of Physics Publishing and Deutsche Physikalische Gesellschaft, 2014-04)
    We propose dynamical control schemes for Hamiltonian simulation in many-body quantum systems that avoid instantaneous control operations and rely solely on realistic bounded-strength control Hamiltonians. Each simulation ...
  • Campagnano, Gabriele; Zilberberg, Oded; Gornyi, Igor V.; Feldman, Dmitri E.; Potter, Andrew Cole; Gefen, Yuval (American Physical Society, 2012-09)
    We present a study of a Hanbury Brown–Twiss interferometer realized with anyons. Such a device can directly probe entanglement and fractional statistics of initially uncorrelated particles. We calculate Hanbury Brown–Twiss ...
  • Rottigni, A.; Carminati, M.; Ferrari, G.; Vahey, M. D.; Voldman, Joel; Sampietro, M. (SPIE, 2011-05)
    Lab-on-a-chip systems have been attracting a growing attention for the perspective of miniaturization and portability of bio-chemical assays. Here we present a the design and characterization of a miniaturized, USB-powered, ...
  • Wetzstein, Gordon; Raskar, Ramesh; Heidrich, Wolfgang (Institute of Electrical and Electronics Engineers (IEEE), 2011-04)
    We introduce a new approach to capturing refraction in transparent media, which we call Light Field Background Oriented Schlieren Photography (LFBOS). By optically coding the locations and directions of light rays emerging ...
  • Jackiw, Roman (Birkhäuser Basel, 2009-03)
    I sketch my experiences with Hans Bethe (1906–2005) as a teacher at Cornell University, beginning with my doctoral studies in 1961 and continuing with my work with him on a quantum-mechanics textbook.
  • Reiling, Jan H.; Clish, Clary; Carette, Jan E.; Varadarajan, Malini; Brummelkamp, Thijn R.; Sabatini, David M. (Proceedings of the National Academy of Sciences (PNAS), 2011-06)
    Tunicamycin (TM) inhibits eukaryotic asparagine-linked glycosylation, protein palmitoylation, ganglioside production, proteoglycan synthesis, 3-hydroxy-3-methylglutaryl coenzyme-A reductase activity, and cell wall biosynthesis ...
  • Ward, Lucas D.; Manolis, Kellis (Oxford University Press, 2011-11)
    The resolution of genome-wide association studies (GWAS) is limited by the linkage disequilibrium (LD) structure of the population being studied. Selecting the most likely causal variants within an LD block is relatively ...
  • Devoto, Florencia; Duflo, Esther; Dupas, Pascaline; Pariente, William; Pons, Vincent (American Economic Association, 2012-11)
    Connecting private dwellings to the water main is expensive and typically cannot be publicly financed. We show that households' willingness to pay for a private connection is high when it can be purchased on credit, not ...
  • Wilczek, Frank (Scientific American, a Division of Nature America/Nature Publishing Group, 2012-05)
    The Higgs gets the headlines, but the electron is really physicists’ favorite particle. The electron theory, developed 120 years ago, is an underappreciated bridge from classical to modern physics.
  • Berger, Emily; Yorukoglu, Deniz; Peng, Jian; Berger, Bonnie (Public Library of Science, 2014-03)
    As the more recent next-generation sequencing (NGS) technologies provide longer read sequences, the use of sequencing datasets for complete haplotype phasing is fast becoming a reality, allowing haplotype reconstruction ...
  • Engel, Michael; Anderson, Joshua A.; Glotzer, Sharon C.; Isobe, Masaharu; Bernard, Etienne P.; Krauth, Werner (American Physical Society, 2013-04)
    We report large-scale computer simulations of the hard-disk system at high densities in the region of the melting transition. Our simulations reproduce the equation of state, previously obtained using the event-chain Monte ...
  • Shah, Devavrat; Tse, David N. C.; Tsitsiklis, John N. (Institute of Electrical and Electronics Engineers (IEEE), 2011-12)
    We consider a communication network and study the problem of designing a high-throughput and low-delay scheduling policy that only requires a polynomial amount of computation at each time step. The well-known maximum weight ...
  • Qiang, Y.; Sparveris, N.; Zhan, X. (American Physical Society, 2013-06)
    We have measured cross sections for the γ[superscript 3]He→pd reaction at photon energies of 0.4–1.4 GeV and a center-of-mass angle of 90°. We observe dimensional scaling above 0.7 GeV at this center-of-mass angle. This ...

    Spinal codes are a recently proposed capacity-achieving rateless code. While hardware encoding of spinal codes is straightforward, the design of an efficient, high-speed hardware decoder poses significant challenges. We ...
