Search for anomalous top quark couplings with the D0 detector
D0 Collaboration, V. Abazov
Anomalous Wtb couplings modify the angular correlations of the top quark decay products and change the single top quark production cross section. We present limits on anomalous top…
The role of striction at magnetic and structural transitions in iron-pnictides
Victor Barzykin, Lev P. Gor'kov
We discuss the role of striction in the intertwined magnetic and structural phase transitions in the underdoped iron-pnictides. The magneto-elastic coupling to acoustic modes is th…
3:1 magnetization plateau and suppression of ferroelectric polarization in an Ising chain multiferroic
Y. J. Jo, Seongsu Lee, E. S. Choi +6
Ferroelectric Ising chain magnet CaCoMnO (0.96) was studied in magnetic fields up to 33 T. Magnetization and neutron scattering measurements reveal suc…
Nuclear Parton Distribution Functions
I. Schienbein, J. Y. Yu, C. Keppel +3
We study nuclear effects of charged current deep inelastic neutrino-iron scattering in the framework of a chi^2 analysis of parton distribution functions (PDFs). We extract a set o…
Multiphoton coherent manipulation in large-spin qubits
S. Bertaina, L. Chen, N. Groll +3
Large spin Mn2+ ions (S=5/2) diluted in a non-magnetic MgO matrix of high crystalline symmetry are used to realize a six level system that can be operated by means of multi-photon…
Incompressibility of neutron-rich matter
J. Piekarewicz, M. Centelles
The saturation properties of neutron-rich matter are investigated in a relativistic mean-field formalism using two accurately calibrated models: NL3 and FSUGold. The saturation pro…
Comment on "Influence of Dzyaloshinskii-Moriya Exchange Interaction on Quantum Phase Interference of Spins"
E. del Barco, S. Hill, D. N. Hendrickson
In a recent Letter [1], Wernsdorfer et al. report an experimental study of a Mn12 molecular wheel which shows essentially identical behavior to the Mn12 wheel studied by Ramsey et…
Space-Efficient Simulation of Quantum Computers
Michael P. Frank, Uwe H. Meyer-Baese, Irinel Chiorescu +2
Traditional algorithms for simulating quantum computers on classical ones require an exponentially large amount of memory, and so typically cannot simulate general quantum circuits…
Beam Spin Asymmetries in DVCS with CLAS at 4 .8 GeV
G. Gavalian
We report measurements of the beam spin asymmetry in Deeply Virtual Compton Scattering (DVCS) at an electron beam energy of 4.8 GeV using the CLAS detector at the Thomas Jefferson…
Metallic Ferromagnetism in the Kondo Lattice
Seiji J. Yamamoto, Qimiao Si
Metallic magnetism is both ancient and modern, occurring in such familiar settings as the lodestone in compass needles and the hard drive in computers. Surprisingly, a rigorous the…
The Experimental Status of Glueballs
V. Crede, C. A. Meyer
Glueballs and other resonances with large gluonic components are predicted as bound states by Quantum Chromodynamics (QCD). The lightest (scalar) glueball is estimated to have a ma…
Virtual Compton Scattering and Neutral Pion Electroproduction in the Resonance Region up to the Deep Inelastic Region at Backward Angles
G. Laveissière
We have made the first measurements of the virtual Compton scattering (VCS) process via the H exclusive reaction in the nucleon resonance region, at backward angles. Resu…
Direct determination of the crystal field parameters of Dy, Er and Yb impurities in the skutterudite compound CeFeP by Electron Spin Resonance
D. J. Garcia, F. A. Garcia, J. G. S. Duque +5
Despite extensive research on the skutterudites for the last decade, their electric crystalline field ground state is still a matter of controversy. We show that Electron Spin Reso…
Algebro-geometric Feynman rules
Paolo Aluffi, Matilde Marcolli
We give a general procedure to construct algebro-geometric Feynman rules, that is, characters of the Connes-Kreimer Hopf algebra of Feynman graphs that factor through a Grothendiec…
First measurement of direct photoproduction on the proton
CLAS Collaboration, M. Battaglieri, R. De Vita +1
We report on the results of the first measurement of exclusive meson photoproduction on protons for GeV and GeV. Data were collected w…
A Uniform Estimate for Fourier Restriction to Simple Curves
Daniel M. Oberlin
We prove a uniform Fourier extension-restriction estimate for a certain class of curves in d-dimensional Euclidean space.
Energy-resolved spatial inhomogeneity of disordered Mott systems
E. C. Andrade, E. Miranda, V. Dobrosavljevic
We investigate the effects of weak to moderate disorder on the T=0 Mott metal-insulator transition in two dimensions. Our model calculations demonstrate that the electronic states…
Resolution-dependent mechanisms for bimodal switching-time distributions in simulated Fe nanopillars
S. H. Thompson, G. Brown, A. Kuhnle +2
We study the magnetization-switching statistics following reversal of the applied field for three separate computational models representing the same physical system, an iron nanop…
Critical behavior at Mott-Anderson transition: a TMT-DMFT perspective
M. C. O. Aguiar, V. Dobrosavljevic, E. Abrahams +1
We present a detailed analysis of the critical behavior close to the Mott-Anderson transition. Our findings are based on a combination of numerical and analytical results obtained…
