  • Charmonium at high temperature in two-flavor QCD 

    PEARDON, MICHAEL JAMES (American Physical Society, 2007)
    We compute charmonium spectral functions in 2-flavor QCD on anisotropic lattices using the maximum entropy method. Our results suggest that the S-waves (J= and c) survive up to temperatures close to 2Tc, while the P-waves ...
  • Charmonium properties in the quark-gluon plasma 

    PEARDON, MICHAEL JAMES (2007)
    We present results for charmonium correlators and spectral functions in 2-flavour QCD on anisotropic lattices. Our results indicate that the S-waves (J/y and hc) survive up to temperatures close to 2Tc, while the P-waves ...
  • Charmonium spectral functions in Nf=2 QCD 

    PEARDON, MICHAEL JAMES; SKULLERUD, JONIVAR (Proceedings of Science, 2005)
    We report on a study of charmonium at high temperature in 2-flavour QCD. This is the first such study with dynamical fermions. Using an improved anisotropic lattice action, spectral functions are extracted from correlators ...
  • Charmonium spectroscopy on dynamical anisotropic lattices 

    PEARDON, MICHAEL JAMES; RYAN, SINEAD MARIE; SKULLERUD, JONIVAR (Elsevier, 2006)
    We present a first study of the charmonium spectrum on Nf = 2 dynamical, anisotropic lattices. We take advantage of all-to-all quark propagators to build spatially extended interpolating operators to increase the overlap ...
  • A comment on "A fast L_p spike alignment metric" by A. J. Dubbs, B. A. Seiler and M. O. Magnasco [arXiv:0907.3137] 

    HOUGHTON, CONOR JAMES (2009)
    Measuring the transmitted information in metric-based clustering has become something of a standard test for the performance of a spike train metric. In this comment, the recently proposed L_p Victor-Purpura metric is used ...
  • Completely bounded mappings and simplicial complex structure in the primitive ideal space of a C*-algebra 

    TIMONEY, RICHARD (American Mathematical Society, 2009)
    We consider the natural contraction from the central Haagerup tensor product of a C*-algebra A with itself to the space of completely bounded maps CB(A) on A and investigate those A where there exists an inverse map ...
  • Deformation of generic submanifolds in a complex manifold 

    ZAITSEV, DMITRI (Elsevier, 2007)
    This paper shows that an arbitrary generic submanifold in a complex manifold can be deformed into a 1-parameter family of generic submanifolds satisfying strong nondegeneracy conditions. The proofs use a careful analysis ...
  • The dressing factor and crossing equations 

    FROLOV, SERGEY (IOP Publishing, 2009)
    We utilize the DHM integral representation for the BES dressing factor of the world-sheet S-matrix of the AdS_5xS^5 light-cone string theory, and the crossing equations to fix the principal branch of the dressing factor ...
  • Excited and exotic charmonium spectroscopy from lattice QCD 

    RYAN, SINEAD MARIE; PEARDON, MICHAEL JAMES (2012)
    We present a spectrum of highly excited charmonium mesons up to around 4.5 GeV calculated using dynamical lattice QCD. Employing novel computational techniques and the variational method with a large basis of carefully ...
  • Factorial states, upper multiplicity and norms of elementary operators 

    TIMONEY, RICHARD (2008)
    Let {pi} be an irreducible representation of a C*-algebra A. We show that the weak* approximation of factorial states associated to {pi} by type I factorial states of lower degree is closely related to the value of the ...
  • Finding community structures in networks by playing pass-the-parcel. 

    HOUGHTON, CONOR JAMES (2008)
    Many data sets can be represented by undirected networks. Often, an interesting and important feature of these networks is the existence of communities; groups of nodes whose interconnectivity is higher than the average ...
  • Five-loop Konishi from the Mirror TBA 

    SUZUKI, RYO; FROLOV, SERGEY (2010)
    We use the Thermodynamic Bethe Ansatz equations for the AdS5 ? S5 mirror model to derive the five-loop anomalous dimension of the Konishi operator. We show numerically that the corresponding result perfectly agrees with ...
  • Free field representation and form factors of the chiral Gross-Neveu model 

    BRITTON, STEPHEN K; FROLOV, SERGEY (2013)
    The free field representation of the Zamolodchikov-Faddeev algebra for the chiral Gross-Neveu model is analysed in detail, and used to construct an integral representation for form factors of the model
  • Generalised Fourier transform for the Camassa-Holm hierarchy 

    IVANOV, ROSSEN (Institute of Physics, 2007)
    The squared eigenfunctions of the spectral problem associated to the Camassa-Holm equation represent a complete basis of functions, which helps to describe the Inverse Scattering Transform for the Camassa-Holm hierarchy ...
  • Giant magnons in TsT-transformed AdS_5 x S^5 

    FROLOV, SERGEY (IOP Publishing, 2008)
    We consider giant magnons propagating in a \gamma-deformed AdS_5 x S^5 background obtained from AdS_5 x S^5 by means of a chain of TsT transformations. We point out that in the light-cone gauge and in the infinite J limit ...
  • Lie group structures on automorphism groups of real-analytic CR manifolds 

    ZAITSEV, DMITRI (The Johns Hopkins University Press, 2008)
    Given any real-analytic CR manifold M, we provide general conditions on M guar- anteeing that the group of all its global real-analytic CR automorphisms AutCR(M) is a Lie group (in an appropriate topology). In particular, ...
  • Mesons at high temperature in Nf=2 QCD 

    PEARDON, MICHAEL JAMES; SKULLERUD, JONIVAR (American Physical Society, 2006)
    We report first results for spectral functions of charmonium in 2-flavour QCD. The spectral functions are determined from vector and pseudoscalar correlators on a dynamical, anisotropic lattice. J/ and c are found ...
  • A metric space approach to the information capacity of spike trains 

    HOUGHTON, CONOR JAMES; GILLESPIE, JAMES (2010)
    Classical information theory can be either discrete or continuous, corresponding to discrete or continuous random variables. However, although spike times in a spike train are described by continuous variables, the ...
  • A novel method for evaluating correlation functions in lattice hadron spectroscopy 

    Peardon, Michael (2010)
    We describe a new approach for evaluating hadronic correlation functions which combines Laplacian-Heaviside quark smearing with a stochastic estimator of quark propagators. This method utilizes noise ...
  • Obstructions to embeddability into hyperquadrics and explicit examples 

    ZAITSEV, DMITRI (Springer, 2008)
    We give series of explicit examples of Levi-nondegenerate real-analytic hypersurfaces in complex spaces that are not transversally holomorphically embeddable into hyperquadrics of any dimension. For this, we construct ...
