  • Díaz, J.S.; Kostelecký, V.A.; Mewes, M. (American Physical Society, 2009)
    The effects of perturbative Lorentz and $CPT$ violation on neutrino oscillations are studied. Features include neutrino-antineutrino oscillations, direction dependence, and unconventional energy behavior. Leading-order ...
  • Kostelecký, V.A.; Samuel, S. (American Physical Society, 1989)
    We investigate measurable gravitational and cosmological effects in four dimensions that can arise from the compactification of higher-dimensional theories incorporating gravity. We identify the nature of effects due to ...
  • Kostelecký, V.A.; Samuel, S. (American Physical Society, 1991)
    We show that string theories allow interactions potentially leading to photon and graviton-mass terms when one or more scalar fields acquire vacuum expectation values. A general analysis is presented for the case when one ...
  • De Juan, F.; Fertig, H.A. (American Physical Society, 2012)
    Phonon dispersions generically display nonanalytic points, known as Kohn anomalies, due to electron-phonon interactions. We analyze this phenomenon for a zone-boundary phonon in undoped graphene. When electron-electron ...
  • Bluhm, R.; Kostelecký, V.A.; Lane, C.D.; Russell, N. (American Physical Society, 2003)
    Space-based experiments offer sensitivity to numerous unmeasured effects involving Lorentz and $CPT$ violation. We provide a classification of clock sensitivities and present explicit expressions for time variations arising ...
  • Kostelecký, V.A.; Tasson, J.D. (American Physical Society, 2009)
    Deviations from relativity are tightly constrained by numerous experiments. A class of unmeasured and potentially large violations is presented that can be tested in the laboratory only via weak-gravity couplings. Specialized ...
  • Bluhm, R.; Kostelecký, V.A. (American Physical Society, 1994)
    We show that a theoretical description of radial Rydberg wave packets in alkali-metal atoms based solely on hydrogenic wave functions and energies is insufficient to explain data that could be obtained in pump-probe ...
  • Murthy, G.; Shimshoni, E.; Shankar, R.; Fertig, H.A. (American Physical Society, 2012)
    We study a generic two-dimensional hopping model on a honeycomb lattice with strong spin-orbit coupling, $\textit{without the requirement that the half-filled lattice be a topological insulator}$. For quarter-(or three-quarter) ...
  • Bluhm, R.; Kostelecký, V.A. (American Physical Society, 1993)
    We outline an analytical framework for the treatment of radial Rydberg wave packets produced by short laser pulses in the absence of external electric and magnetic fields. Wave packets of this type are localized in the ...
  • Jackiw, R.; Kostelecký, V.A. (American Physical Society, 1999)
    In a nonperturbative formulation, radiative corrections arising from Lorentz and $CPT$ violation in the fermion sector induce a definite and nonzero Chern-Simons addition to the electromagnetic action. If instead a ...
  • Bailey, J.A.; Bazavov, A.; Bernard, C.; Bouchard, C.M.; DeTar, C.; Du, D.; El-Khadra, A.X.; Foley, J.; Freeland, E.D.; Gámiz, E.; ... (American Physical Society, 2012)
    The semileptonic decay channel $B\rightarrow D_{\tau\nu}$ is sensitive to the presence of a scalar current, such as that mediated by a charged-Higgs boson. Recently, the $\textit{BABAR}$ experiment reported the first ...
  • Díaz, J.S.; Kostelecký, V.A.; Lehnert, R. (American Physical Society, 2013)
    In some quantum theories of gravity, deviations from the laws of relativity could be comparatively large while escaping detection to date. In the neutrino sector, precision experiments with beta decay yield new and improved ...
  • Kostelecký, V.A.; Nieto, M.M. (American Physical Society, 1991)
    The preceding paper, by Martin and Barrientos [Phys. Rev. A 43, 4061 (1991)], comments on our supersymmetry-inspired model of atomic physics. We relate this to other Comments [Rau, Phys. Rev. Lett. 56, 95 (1986) and ...
  • Kostelecký, V.A.; Nieto, M.M.; Truax, D.R. (American Physical Society, 1990)
    The preceding Comment by Goodfriend [Phys. Rev. A 41, 1730 (1990)] contains three criticisms of our model for analytical quantum-defect wave functions vis-á-vis the atomic Fues potential of Simons [J. Phys. Chem. 55, 756 ...
  • Bluhm, R.; Kostelecký, V.A.; Tudose, B. (American Physical Society, 1997)
    The revival structure of Stark wave packets is considered. These wave packets have energies depending on two quantum numbers and are characterized by two sets of classical periods and revival times. The additional time ...

  • Ablikim, M.; Achasov, M.N.; Ambrose, D.J.; An, F.F.; An, Q.; An, Z.H.; Bai, J.Z.; Ban, Y.; Becker, J.; Berger, N.; ... (American Physical Society, 2012)
    Using a data sample containing $1.06×10^8 ψ^′$ events collected with the BESIII detector at the BEPCII electron-positron collider, we search for a light exotic particle X in the process $ψ′→π^+π^−J/ψ, J/ψ→γX, X→μ^+μ^−$. ...

    We report a search for a narrow $t\bar t$ resonance that decays into a $\text{lepton+jets}$ final state based on an integrated luminosity of $5.3 \text{ fb}^{−1}$ of proton-antiproton collisions at $\sqrt s=1.96\ \text{TeV}$ ...

    We report on a search for charged massive long-lived particles (CMLLPs), based on $5.2  \text{fb}^{−1}$ of integrated luminosity collected with the D0 detector at the Fermilab Tevatron $p\bar p$ collider. We search for ...
