Gauge invariant Hamiltonian formulation of lattice YangMills theory
(World Scientific, 1995)It it known that to get the usual Hamiltonian formulation of lattice YangMills theory in the temporal gauge A0 = 0 one should place on every link the cotangent bundle of a Lie group. The cotangent bundle may be considered ... 
Gauge theories on a 2+2 anisotropic lattice
(American Physical Society, 2003)The implementation of gauge theories on a fourdimensional anisotropic lattice with two distinct lattice spacings is discussed, with special attention to the case where two axes are finely and two axes are coarsely discretized. ... 
Gaugestring duality for (non)supersymmetric deformations of N=4 super YangMills theory.
(Elsevier, 2005)We consider a nonsupersymmetric example of the AdS/CFT duality which generalizes the supersymmetric exactly marginal deformation constructed in hepth/0502086. The string theory background we use was found in hepth/0503201 ... 
Gaugestring duality for superconformal deformations of N=4 super YangMills theory.
(Institute of Physics, 2005)We analyze in detail the relation between an exactly marginal deformation of N = 4 SYM  the LeighStrassler or \?deformation"  and its string theory dual (recently constructed in hepth/0502086) by comparing energies ... 
Generalised Fourier transform for the CamassaHolm hierarchy
(Institute of Physics, 2007)The squared eigenfunctions of the spectral problem associated to the CamassaHolm equation represent a complete basis of functions, which helps to describe the Inverse Scattering Transform for the CamassaHolm hierarchy ... 
Giant magnons in TsTtransformed AdS_5 x S^5
(IOP Publishing, 2008)We consider giant magnons propagating in a \gammadeformed 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 lightcone gauge and in the infinite J limit ... 
Glueball matrix elements on anisotropic lattices
(Elsevier, 1998)We describe a lattice calculation of the matrix elements relevant for glueball production in J/ radiative decays. The techniques for such a calculation on anisotropic lattices with an improved action are outlined. We ... 
Glueball matrix elements on anisotropic lattices
(Elsevier, 2004)The glueballtovacuum matrix elements of local gluonic operators in scalar, tensor, and pseudoscalar channels are investigated numerically on several anisotropic lattices with the spatial lattice spacing in the range ... 
Glueball spectrum and matrix elements on anisotropic lattices
(American Physical Society, 2006)The glueballtovacuum matrix elements of local gluonic operators in scalar, tensor, and pseudoscalar channels are investigated numerically on several anisotropic lattices with the spatial lattice spacing ranging from ... 
Glueball spectrum from an anisotropic lattice study
(American Physical Society, 1999)The spectrum of glueballs below 4 GeV in the SU~3! puregauge theory is investigated using Monte Carlo simulations of gluons on several anisotropic lattices with spatial grid separations ranging from 0.1 to 0.4 fm. Systematic ... 
The glueball spectrum from novel improved actions
(Elsevier, 2000)Results for the interquark potential and lowlying SU(3) glueball spectrum from simulations using a new improved action are presented. The action, suitable for highly anisotropic lattices, contains a twoplaquette ... 
GreenSchwarz strings in TsTtransformed backgrounds.
(Institute of Physics, 2006)We consider classical strings propagating in a background generated by a sequence of TsT transformations. We describe a general procedure to derive the GreenSchwarz action for strings. We show that the U(1) isometry ... 
Hadron spectroscopy from lattice quantum chromodynamics
(2016)Lattice calculations of hadron spectroscopy are discussed. A brief introduction to numerical simulations of QCD, with a focus on spectroscopy is given. Results for spectroscopy of lowlying, excited and exotic states ... 
Haldane limits via Lagrangian embeddings
(Elsevier, 2012)In the present paper we revisit the socalled Haldane limit, i.e. a particular continuum limit, which leads from a spin chain to a sigma model. We use the coherent state formulation of the path integral to reduce the problem ... 
Hamiltonian lattice gauge models and the Heisenberg double
(World Scientific, 1995)Hamiltonian lattice gauge models based on the assignment of the Heisenberg double of a Lie group to each link of the lattice are constructed in arbitrary spacetime dimensions. It is shown that the corresponding generalization ... 
Heavy hadrons on an anisotropic lattice
(Elsevier, 2004)Results from simulations of quarkonia and heavylight mesons on an anisotropic lattice are presented. The improved quark action and actionparameter tuning used in this study are discussed. 
Heavy quark physics from lattice QCD
(Elsevier, 2002)I review the current status of lattice calculations of heavy quark quantities. Particular emphasis is placed on leptonic and semileptonic decay matrix elements. 
Higgs Bundles, Gauge Theories and Quantum Groups
(2008)The appearance of the Bethe Ansatz equation for the Nonlinea r Schr ?odinger equa tion in the equivariant integration over the moduli space of Higgs bundles is revisited. We argue that the wave functions of the ... 
High performance scientific computing using FPGAS with IEEE floating point and logarithmic arithmetic for lattice QCD
(IEEE, 2006)The recent development of large FPGAs along with the availability of a variety of floating point cores have made it possible to implement highperformance matrix and vector kernel operations on FPGAs. In this paper we seek ...
