    • Very large magnetoresistance in Fe0.28TaS2 single crystals 

      Hardy, Will J.; Chen, Chih-Wei; Marcinkova, A.; Ji, Heng; Sinova, Jairo; Natelson, D.; Morosan, E. (2015)
      Magnetic moments intercalated into layered transition metal dichalcogenides are an excellent system for investigating the rich physics associated with magnetic ordering in a strongly anisotropic, strong spin-orbit coupling ...
    • Very strong Rydberg atom scattering in K(12p)–CH3NO2collisions: Role of transient ion pair formation 

      Kelley, M.; Buathong, S.; Dunning, F.B. (2017)
      Collisions between K(12p) Rydberg atoms and CH3NO2 target molecules are studied. Whereas CH3NO2 can form long-lived valence-bound CH3NO−2NO2− ions, the data provide no evidence for production of long-lived K+⋯⋯CH3NO−2NO2− ion ...
    • Voltage tuning of vibrational mode energies in single-molecule junctions 

      Li, Yajing; Doak, Peter; Kronik, Leeor; Neaton, Jeffrey B.; Natelson, Douglas (2014)
      Vibrational modes of molecules are fundamental properties determined by intramolecular bonding, atomic masses, and molecular geometry, and often serve as important channels for dissipation in nanoscale processes. Although ...
    • Wafer-scale monodomain films of spontaneously aligned single-walled carbon nanotubes 

      He, Xiaowei; Gao, Weilu; Xie, Lijuan; Li, Bo; Zhang, Qi; Lei, Sidong; Robinson, John M.; Hároz, Erik H.; Doorn, Stephen K.; Wang, Weipeng; Vajtai, Robert; Ajayan, Pulickel M.; Adams, W. Wade; Hauge, Robert H.; Kono, Junichiro (2016)
      The one-dimensional character of electrons, phonons and excitons in individual single-walled carbon nanotubes leads to extremely anisotropic electronic, thermal and optical properties. However, despite significant efforts ...
    • Weaker nematic phase connected to the first order antiferromagnetic phase transition inᅠSrFe2As2ᅠcompared toᅠBaFe2As2 

      Tam, David W.; Wang, Weiyi; Zhang, Li; Song, Yu; Zhang, Rui; Carr, Scott V.; Walker, H.C.; Perring, Toby G.; Adroja, D.T.; Dai, Pengcheng (2019)
      Understanding the nature of the electronic nematic phase in iron pnictide superconductors is important for elucidating its impact on high-temperature superconductivity. Here we use transport and inelastic neutron scattering ...
    • Weyl–Kondo semimetal in heavy-fermion systems 

      Lai, Hsin-Hua; Grefe, Sarah E.; Paschen, Silke; Si, Qimiao (2018)
      While electronic states with nontrivial topology have traditionally been known in insulators, they have been evidenced in metals during the past 2 years. Such Weyl semimetals show topological protection while conducting ...
    • Why hydrocarbon-cross-linked peptides are membrane permeable 

      Sun, Tzu-Lin; Lee, Chang-Chun; Sun, Yen; Huang, Huey W. (2012)
    • Widespread orthorhombic fluctuations in the (Sr,Na)Fe2As2 family of superconductors 

      Frandsen, Benjamin A.; Taddei, Keith M.; Bugaris, Daniel E.; Stadel, Ryan; Yi, Ming; Acharya, Arani; Osborn, Raymond; Rosenkranz, Stephan; Chmaissem, Omar; Birgeneau, Robert J. (2018)
      We report comprehensive pair distribution function measurements of the hole-doped iron-based superconductor system Sr1−xNaxFe2As2. Structural refinements performed as a function of temperature and length scale reveal ...
    • X-Ray and Radio Observations of the Magnetar SGR J1935+2154 during Its 2014, 2015, and 2016 Outbursts 

      Younes, George; Kouveliotou, Chryssa; Jaodand, Amruta; Baring, Matthew G.; van der Horst, Alexander J.; Harding, Alice K.; Hessels, Jason W.T.; Gehrels, Neil; Gill, Ramandeep; Huppenkothen, Daniela; Granot, Jonathan; Göğüş Ersin; Lin, Lin (2017)
      We analyzed broadband X-ray and radio data of the magnetar SGR J1935+2154 taken in the aftermath of its 2014, 2015, and 2016 outbursts. The source soft X-ray spectrum <10 keV is well described with a blackbody+power-law ...
    • X-ray laser implementation by means of a strong source of high-spin metastable atoms 

      Helman, J.S.; Rau, C.; Bunge, C.F. (1983)
      High-spin metastable atomic beams of high density and extremely small divergence can be produced by electron capture during grazing-angle scattering of ion beams at ferromagnetic surfaces. This can be used to generate a ...
    • β-YbAlB4: A Critical Nodal Metal 

      Ramires, Aline; Coleman, Piers; Nevidomskyy, Andriy H.; Tsvelik, A. M. (2012-10)
      We propose a model for the intrinsic quantum criticality of β-YbAlB4, in which a vortex in momentum space gives rise to a new type of Fermi surface singularity. The unquenched angular momentum of the |J=7/2,mJ=±5/2⟩ Yb 4f ...

      STAR Collaboration; Eppley, G.; Geurts, F.; Liu, J.; Llope, W.J.; McDonald, D.; Roberts, J.B.; Yepes, P. (2012)
      Vector mesons may be photoproduced in relativistic heavy-ion collisions when a virtual photon emitted by one nucleus scatters from the other nucleus, emerging as a vector meson. The STAR Collaboration has previously presented ...
