  • Newhouse, Paul F.; Park, C.-H.; Keszler, Douglas A.; Tate, J.; Nyholm, P. S. (American Institute of Physics, 2005-09-09)
    High electron mobility thin films of In₂₋ₓWₓO₃₊y(0≤x≤0.075) were prepared on amorphous SiO₂ and single-crystal yttria-stablized zirconia (001) substrates by pulsed laser deposition. Mobilities ranged between 66 and 112 ...

    We demonstrate terahertz (THz) imaging and spectroscopy of single-layer graphene deposited on an intrinsic Si substrate using THz time-domain spectroscopy. A single-cycle THz pulse undergoes multiple internal reflections ...
  • Paul, M. J.; Chang, Y. C.; Thompson, Z. J.; Stickel, A.; Wardini, J.; Choi, H.; Minot, E. D.; Norris, T. B.; Lee, Yun-Shik (IOP Publishing Ltd, 2013-08-22)
    We investigate the response of multi-layer epitaxial graphene and chemical vapor deposition (CVD)-grown single-layer graphene to strong terahertz (THz) fields. Contrary to theoretical predictions of strong nonlinear resp ...
  • Tom, D. W.; Platzer, R.; Gardner, John A.; Tate, J. (The American Institute of Physics, 1993-09-27)
    Radioactive In has been incorporated into oriented thin films of YBa₂Cu₃O₇₋δ during a thermal coevaporation process. The hyperfme technique of perturbed γγ-angular correlation spectroscopy shows that 60% of the indium ...
  • Chien, Chih-Chun; Gruss, Daniel; Di Ventra, Massimiliano; Zwolak, Michael (IOP Publishing Ltd and Deutsche Physikalische Gesellschaft, 2013-06-19)
    The study of time-dependent, many-body transport phenomena is increasingly within reach of ultra-cold atom experiments. We show that the introduction of spatially inhomogeneous interactions, e.g., generated by optically ...
  • Jeong, Young-Gyun; Paul, Michael J.; Kim, Seung-Hyun; Yee, Ki-Ju; Kim, Dai-Sik; Lee, Yun-Shik (American Institute of Physics Publishing, 2013-10-21)
    We demonstrate remarkably strong nonlinear terahertz (THz) effects in an intrinsic GaAs wafer patterned with a nanometer-width slot antenna array. The antenna near-field reaches 20 MV/cm due to the huge field enhancement ...
  • Wasserman, A. (The American Institute of Physics, 1967-02-15)
    Electron avalanche due to intraband optical absorption is discussed as a mechanism responsible for laser induced damage in certain insulating crystals.
  • Hoffman, Anthony J.; Sridhar, Aishwarya; Braun, Phillip X.; Alekseyev, Leonid; Howard, Scott S.; Franz, Kale J.; Cheng, Liwei; Choa, Fow-Sen; Sivco, Deborah L; Podolskiy, Viktor A.; Narimanov, Evgenii E.; Gmachl, Claire (American Institute of Physics, 2009-06-18)
    We report on a novel class of semiconductor metamaterials that employ a strongly anisotropic dielectric function to achieve negative refraction in the midinfrared region of the spectrum, ~8.5–13 μm. We present two type ...
  • Elser, Justin; Wangberg, Robyn; Podolskiy, Viktor A.; Narimanov, Evgenii E. (American Institute of Physics, 2006-12-26)
    The authors study perspectives of nanowire metamaterials for negative-refraction waveguides, high-performance polarizers, and polarization-sensitive biosensors. They demonstrate that the behavior of these composites is ...
  • Sun, Bo; Duclos, Guillaume; Stone, Howard A. (American Physical Society, 2013-04-09)
    The collective chemosensing of nonexcitable mammalian cells involves a biochemical network that features gap junction communications and heterogeneous single cell activities. To understand the integrated multicellular ch ...
  • Dauenhauer, A. Y.; Krane, K. S. (American Physical Society, 2012-06-04)
    Cross sections for radiative capture of neutrons have been measured by the activation technique for stable isotopes of Ba with mass numbers 130, 132, 134, 136, and 138. From separate irradiations using thermal and epithe ...
  • Torrel, S.; Krane, K. S. (American Physical Society, 2012-09-27)
    The activation method has been used to measure the cross sections for radiative capture of neutrons by all isotopes of stable Ce (mass numbers 136, 138, 140, and 142). Both the thermal cross sections and the resonance in ...
  • Krane, K. S. (American Physical Society, 2012-04-23)
    Radiative neutron capture cross sections have been measured for the stable isotopes of natural Os with mass numbers 184, 189, 190, and 192 by observing radioactive decays of the activation products following neutron irra ...

  • Dziarmaga, Jacek; Zurek, Wojciech H.; Zwolak, Michael (Nature Publishing Group, 2011-12-11)
    Topological defects, such as monopoles, vortex lines or domain walls, mark locations where disparate choices of a broken-symmetry vacuum elsewhere in the system lead to irreconcilable differences(1,2). They are energetic ...
  • Elser, Justin; Podolskiy, Viktor A.; Salakhutdinov, Ildar; Avrutsky, Ivan (American Institute of Physics, 2007-05-08)
    The authors analyze electromagnetic modes in multilayered nanocomposites and demonstrate that the response of a majority of realistic layered structures is strongly affected by the nonlocal effects originating from str ...
  • Podolskiy, Viktor A.; Kuhta, Nicholas A.; Milton, Graeme W. (American Institute of Physics, 2005-11-30)
    We analyze the performance of a planar lens based on realistic negative index material in a generalized geometry. We demonstrate that the conventional superlens design (where the lens is centered between the object and ...
