  • Kostelecký, V.A.; Mewes, M. (American Physical Society, 2013)
    The theoretical description of fermions in the presence of Lorentz and CPT violation is developed. We classify all Lorentz- and CPT-violating and invariant terms in the quadratic Lagrange density for a Dirac fermion, ...
  • Kostelecký, V.A.; Nieto, M.M.; Truax, D.R. (American Physical Society, 1988)
    We investigate the domain of validity of previously proposed analytical wave functions for atomic quantum-defect theory. This is done by considering the fine-structure splitting of alkali-metal and singly ionized alkaline-earth ...
  • Grushin, A.G.; De Juan, F. (American Physical Society, 2012)
    Topological insulators with a time-reversal symmetry-breaking perturbation near the surface present a magnetoelectric response that is quantized when the frequency of the probing fields is much smaller than the surface gap ...
  • Ablikim, M.; Achasov, M.N.; Alberto, D.; Ambrose, D.J.; An, F.F.; An, Q.; An, Z.H.; Bai, J.Z.; Baldini Ferroli, R.B.F.; Ban, Y.; ... (American Physical Society, 2012)
    The decays $J/\psi\rightarrow\gamma\pi^+\pi^-\pi^0$ and $J/\psi\rightarrow\gamma\pi^0\pi^0\pi^0$ are analyzed using a sample of $225\times10^6$ $J/\psi$ events collected with the BESIII detector. The decay of $\eta(1405) ...
  • 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 sample of $(225.2±2.8)×10^6$ $J/\psi$ events collected with the BESIII detector, we present results of a study of $J/\psi→\gamma\mathit{\Lambda\overline{\Lambda}}$ and report the first observation of the isospin ...
  • 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 sample of $106×10^6$ $\psi(3686)$ events collected with the BESIII detector at the BEPCII storage ring, we have made the first measurement of the $M1$ transition between the radially excited charmonium $S-wave$ ...
  • Bazavov, A.; Bhattacharya, T.; DeTar, C.E.; Ding, H.-T.; Gottlieb, S.; Gupta, R.; Hegde, P.; Heller, U.M.; Karsch, F.; Laermann, E.; ... (American Physical Society, 2012)
    We calculate the quadratic fluctuations of net baryon number, electric charge and strangeness as well as correlations among these conserved charges in $(2+1)$-flavor lattice QCD at zero chemical potential. Results are ...
  • Thampy, V.; Kang, J.; Rodriguez-Rivera, J.A.; Bao, W.; Savici, A.T.; Hu, J.; Liu, T.J.; Qian, B.; Fobes, D.; Mao, Z.Q.; ... (American Physical Society, 2012)
    Using polarized and unpolarized neutron scattering, we show that interstitial Fe in superconducting $\text{Fe}_{1+y}$ $\text{Te}_{1−x}$ $\text{Se}_x$ induces a magnetic Friedel-like oscillation that diffracts at $Q_⊥=(\frac{1}{2} ...
  • Isaev, L.; Ortiz, G. (American Physical Society, 2012)
    We develop a general framework, which combines exact diagonalization in small clusters with a density matrix variational principle, to study frustrated magnets at finite temperature. This thermodynamic hierarchical mean-field ...

    Das, Narayan (2013-02-14)
  • Katori, T.; Kostelecký, V.A.; Tayloe, R. (American Physical Society, 2006)
    A model of neutrino oscillations is presented that has only 3 degrees of freedom and appears compatible with existing data. The model is a subset of the renormalizable sector of the Standard-Model Extension (SME), and it ...
  • Kostelecký, V.A.; Samuel, S. (American Physical Society, 1989)
    We investigate gravitational phenomenology in compactified higher-dimensional theories, with particular emphasis on the consequences in string theory of tensor-induced spontaneous Lorentz-symmetry breaking. The role played ...
  • Kostelecký, V.A.; Potting, R. (American Physical Society, 2009)
    We investigate a class of theories involving a symmetric two-tensor field in Minkowski spacetime with a potential triggering spontaneous violation of Lorentz symmetry. The resulting massless Nambu-Goldstone modes are shown ...
  • Kostelecký, V.A. (American Physical Society, 2004)
    The role of the gravitational sector in the Lorentz- and CPT-violating standard-model extension (SME) is studied. A framework is developed for addressing this topic in the context of Riemann-Cartan spacetimes, which include ...
  • Horowitz, C.J.; Piekarewicz, J. (American Physical Society, 2012)
    Background: Measurements of neutron radii provide important constraints on the isovector sector of nuclear density functionals and offer vital guidance in areas as diverse as atomic parity violation, heavy-ion collisions, ...
  • Abazov, V.M.; Abbott, B.; Acharya, B.S.; Adams, M.; Adams, T.; Alexeev, G.D.; Alkhazov, G.; Alton, A.; Alverson, G.; Aoki, M.; ... (American Physical Society, 2012)
    We present an improved determination of the total width of the top quark, $\Gamma_t$, using $5.4  \text{fb}^{−1}$ of integrated luminosity collected by the D0 Collaboration at the Tevatron $p\bar p$ Collider. The total ...

    We report an improved measurement of $\overline{\nu}_μ$ disappearance over a distance of 735 km using the MINOS detectors and the Fermilab Main Injector neutrino beam in a $\overline{\nu}_μ$-enhanced configuration. From a ...

    In this paper we present a multiscale, individual-based simulation environment that integrates CompuCell3D for lattice-based modelling on the cellular level and Bionetsolver for intracellular modelling. CompuCell3D or CC3D ...
  • Bluhm, R.; Kostelecký, V.A.; Tudose, B. (American Physical Society, 1996)
    We construct minimum-uncertainty solutions of the three-dimensional Schrödinger equation with a Coulomb potential. These wave packets are localized in radial and angular coordinates and are squeezed states in three dimensions. ...
  • Kostelecký, V.A.; Nieto, M.M. (American Physical Society, 1986)
    A reply to the comment on evidence for a phenomenological supersymmetr in atomic physics is presented.
