  • Rigolin, G.; Ortiz, G. (American Physical Society, 2012)
    By stating the adiabatic theorem of quantum mechanics in a clear and rigorous way, we establish a necessary condition and a sufficient condition for its validity, where the latter is obtained employing our recently developed ...
  • Guo, P.; Mitchell, R.; Shepherd, M.; Szczepaniak, A.P. (American Physical Society, 2012)
    We construct an analytical model for two-channel, two-body scattering amplitudes, and then apply it in the description of the three-body $J/ψ→K^+K^−π^0$ decay. In the construction of the partial wave amplitudes, we combine ...
  • Kostelecký, V.A.; Roberts, A. (American Physical Society, 2001)
    Analogue models for $CP$ violation in neutral-meson systems are studied in a general framework. No-go results are obtained for models in classical mechanics that are nondissipative or that involve one-dimensional oscillators. ...
  • Kostelecký, V.A.; Potting, R. (American Physical Society, 2001)
    Using analytical methods, a nonperturbative vacuum is constructed recursively in the field theory for the open bosonic string. Evidence suggests it corresponds to the Lorentz-invariant end point of tachyon condensation on ...
  • Kostelecký, V.A.; Nieto, M.M. (American Physical Society, 1985)
    We present an exactly solvable effective potential that reproduces atomic spectra in the limit of exact quantum-defect theory, i.e., the limit in which, for a fixed l, the principal quantum number is modified by a constant: ...
  • Nussinov, Z.; Ortiz, G.; Cobanera, E. (American Physical Society, 2012)
    Motivated by the prospect of attaining Majorana modes at the ends of nanowires, we analyze interacting Majorana systems on general networks and lattices in an arbitrary number of dimensions, and derive universal spin duals. ...
  • Kostelecký, V.A.; Mewes, M. (IOP Publishing, 2008)
    A general framework for tests of Lorentz invariance with electromagnetic waves is presented, allowing for operators of arbitrary mass dimension. Signatures of Lorentz violations include vacuum birefringence, vacuum dispersion, ...
  • Bluhm, R.; Kostelecký, V.A. (American Physical Society, 1993)
    A search is conducted for physical quantum-mechanical supersymmetries involving the hydrogen atom. In all coordinate systems admitting a direct separation of the Schrödinger equation, the structure of the separated equations ...
  • Bluhm, R.; Kostelecký, V.A. (American Physical Society, 1994)
    We study radial wave packets produced by short-pulsed laser fields acting on Rydberg atoms, using analytical tools from supersymmetry-based quantum-defect theory. We begin with a time-dependent perturbative calculation for ...
  • Bazavov, A.; Bernard, C.; Bouchard, C.M.; DeTar, C.; Di Pierro, M.; El-Khadra, A.X.; Evans, R.T.; Freeland, E.D.; Gámiz, E.; Gottlieb, S.; ... (American Physical Society, 2012)
    We calculate the leptonic decay constants of $B_{(s)}$ and $D_{(s)}$ mesons in lattice QCD using staggered light quarks and Fermilab bottom and charm quarks. We compute the heavy-light-meson correlation functions on the ...
  • Beggs, J.M.; Timme, N. (Frontiers Media S.A., 2012)
    Relatively recent work has reported that networks of neurons can produce avalanches of activity whose sizes follow a power law distribution. This suggests that these networks may be operating near a critical point, poised ...
  • Kostelecký, V.A.; Russell, N.; Tso, R. (Elsevier, 2012)
    Bipartite Riemann–Finsler geometries with complementary Finsler structures are constructed. Calculable examples are presented based on a bilinear-form coefficient for explicit Lorentz violation.
  • Kostelecký, V.A.; Van Kooten, R. (American Physical Society, 1996)
    The feasibility of placing bounds on $CPT$ violation from experiments with neutral $B$ mesons is examined. We consider situations with uncorrelated mesons and ones with either unboosted or boosted correlated mesons. ...
  • Canè, F.; Bear, D.; Phillips, D.F.; Rosen, M.S.; Smallwood, C.L.; Stoner, R.E.; Walsworth, R.L.; Kostelecký, V.A. (American Physical Society, 2004)
    A search for an annual variation of a daily sidereal modulation of the frequency difference between colocated $^{129}\text{Xe}$ and $^{3}\text{He}$ Zeeman masers sets a stringent limit on boost-dependent Lorentz and $CPT$ ...
  • 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)
    We calculate form-factor ratios between the semileptonic decays $\overline{B}^{0} \rightarrow D^{+}\ell^{-}\overline{\nu}$ and $\overline{B}^{0}_{s} \rightarrow D^{+}_{s}\ell^{-}\overline{\nu}$ with lattice QCD. These ...
  • Horowitz, C.J.; Shen, G.; O'Connor, Evan; Ott, Christian D. (American Physical Society, 2012)
    Core-collapse supernovae may depend sensitively on charged-current neutrino interactions in warm, low-density, neutron-rich matter. A proton in neutron-rich matter is more tightly bound than is a neutron. This energy shift ...
  • Bazavov, A.; Bhattacharya, T.; Cheng, M.; DeTar, C.E.; Ding, H.-T.; Gottlieb, S.; Gupta, R.; Hedge, P.; Heller, U.M.; Karsch, F.; ... (American Physical Society, 2012)
    We present results on the chiral and deconfinement properties of the QCD transition at finite temperature. Calculations are performed with 2+1 flavors of quarks using the p4, asqtad, and HISQ/tree actions. Lattices with ...
  • Kostelecký, V.A.; Russell, N. (Elsevier, 2010)
    Classical point-particle relativistic lagrangians are constructed that generate the momentum–velocity and dispersion relations for quantum wave packets in Lorentz-violating effective field theory.
