    • Temperature dependent photoluminescence from porous silicon nanostructures: Quantum confinement and oxide related transitions 

      Ray, Mallar; Bandyopadhyay, Nil Ratan; Ghanta, Ujjwal; Klie, Robert F.; Pramanick, Ashit Kumar (American Institute of Physics, 2011-11)
      Temperature dependent photoluminescence (PL) spectroscopy along with structural investigations of luminescent porous Si enable us to experimentally distinguish between the relative contributions of band-to-band and oxide ...
    • Temperature-Dependent Three-Dimensional Anisotropy of the Magnetoresistance in WTe2 

      Thoutam, LR; Wang, YL; Xiao, ZL; Das, S.; Luican-Mayer, A.; Divan, R.; Crabtree, GW; Kwok, WK (American Physical Society, 2015-07-22)
      Extremely large magnetoresistance (XMR) was recently discovered in WTe2, triggering extensive research on this material regarding the XMR origin. Since WTe2 is a layered compound with metal layers sandwiched between adjacent ...
    • Total Width of 125 GeV Higgs Boson 

      Barger, Vernon; Ishida, Muneyuki; Keung, Wai-Yee (American Physical Society, 2012-06)
      By using the LHC and Tevatron measurements of the cross sections to various decay channels relative to the standard model Higgs boson, the total width of the putative 125 GeV Higgs boson is determined as 6:1þ7:7 2:9 ...
    • Twist-open mechanism of DNA damage recognition by the Rad4/XPC nucleotide excision repair complex. 

      Velmurugu, Y; Chen, X; Slogoff Sevilla, P (National Academy of Sciences, 2016-04-19)
      DNA damage repair starts with the recognition of damaged sites from predominantly normal DNA. In eukaryotes, diverse DNA lesions from environmental sources are recognized by the xeroderma pigmentosum C (XPC) nucleotide ...
    • Two- to three-dimensional crossover in the electronic structure of (Bi,Pb)2(Sr,La)2CuO6+delta from angle-resolved photoemission spectroscopy 

      Tsunehiro, Takeuchi; Takeshi, Kondo; Takio, Kitao; Hiroyuki, Kaga; Hongbo, Yang; Hong, Ding; Adam, Kaminski; Juan Carlos, Campuzano (American Physical Society, 2005-11-25)
      The hole-concentration (x) dependence of the three-dimensional energy-momentum dispersion in (Bi,Pb)(2)(Sr,La)(2)CuO6+delta has been investigated by angle-resolved photoemission spectroscopy. For a heavily overdoped sample ...
    • Universality of Plasmon Excitations in Dirac Semimetals 

      Kharzeev, D. E.; Pisarski, R. D.; Yee, H. U. (American Physical Society, 2015-12-02)
      We investigate the properties of the collective plasmon excitations in Dirac semimetals by using the methods of relativistic field theory. We find a strong and narrow plasmon excitation whose frequency is in the terahertz ...
    • Universality of Plasmon Excitations in Dirac Semimetals. 

      Kharzeev, DE; Pisarski, RD; Yee, HU (American Physical Society, 2015-12-04)
      We investigate the properties of the collective plasmon excitations in Dirac semimetals by using the methods of relativistic field theory. We find a strong and narrow plasmon excitation whose frequency is in the terahertz ...
    • Vortex cutting in superconductors. 

      Glatz A; Vlasko-Vlasov VK; Kwok WK; Crabtree GW (American Physical Society, 2016-08-09)
      Vortex cutting and reconnection is an intriguing and still-unsolved problem central to many areas of classical and quantum physics, including hydrodynamics, astrophysics, and superconductivity. Here, we describe ...
    • Water at functional interfaces 

      Garde, S.; Schlossman, M.L. (Cambridge University Press, 2014-12)
      Water is, perhaps, the most important material known to humankind—fascinating even in its pure state for the range of anomalous properties it displays. There has been increasing realization that understanding the behavior ...
    • X-ray fluorescence from a model liquid/liquid solvent extraction system 

      Bu, Wei; Hou, Binyang; Mihaylov, Miroslav; Kuzmenko, Ivan; Lin, Binhua; Meron, Mati; Soderholm, L.; Luo, Guangming; Schlossman, Mark L. (American Institute of Physics, 2011-11-15)
      X-ray fluorescence near total reflection (XFNTR) is measured from the liquid/liquid interface between dodecane and an ErCl3 aqueous solution by monitoring L shell Er emission lines. A custom sample cell is used to minimize ...
    • X-ray resonant magnetic scattering study of magnetization reversals in a nanoscale spin-valve array 

      Lee, Dong Ryeol; Freeland, John W.; Choi, Yongseong; Srajer, George; Metlushko, Vitali; Ilic, Bojan (American Physical Society, 2007-10)
      We present an x-ray resonant magnetic scattering study that uses the periodicity of a patterned array of trilayer (Co/Cu/NiFe) elements to determine not only layer-dependent magnetic hysteresis, but, more importantly, to ...
