Constraints on $m_s$ and $\epsilon'/\epsilon$ from Lattice QCD

open access: yes, 2000
Results for light quark masses obtained from lattice QCD simulations are compared and contrasted with other determinations. Relevance of these results to estimates of $\epsilon'/\epsilon$ is discussed.Comment: Latex, 7 pages, 2 figures.

SU(N) Antiferromagnets and Strongly Coupled QED: Effective Field Theory for Josephson Junctions Arrays

open access: yes, 1993
We review our analysis of the strong coupling of compact QED on a lattice with staggered Fermions. We show that, for infinite coupling, compact QED is exactly mapped in a quantum antiferromagnet.

Monopoles and Chaos [PDF]

open access: yes, 2002
We decompose U(1) gauge fields into a monopole and photon part across the phase transition from the confinement to the Coulomb phase. We analyze the leading Lyapunov exponents of such gauge field configurations on the lattice which are initialized by ...

Structure Functions on the lattice [PDF]

open access: yes, 2000
We report on a lattice computation of the second moment of the pion matrix element of the twist-2 non-singlet operator corresponding to the average momentum of parton densities.

Quantum Monte Carlo approaches to nuclear and atomic physics

open access: yes, 2012
Quantum Monte Carlo methods have proven to be valuable in the study of strongly correlated quantum systems, particularly nuclear physics and cold atomic gases.

Connecting structure functions on the lattice with phenomenology

open access: yes, 2001
We examine the extraction of moments of parton distributions from lattice data, focusing in particular on the chiral extrapolation as a function of the quark mass.

Recent results from Lattice QCD

open access: yes, 2014
Recent Lattice QCD results are reviewed with an emphasis on spectroscopic results concerning the charm quark. It is demonstrated that, with accurate computations from lattice QCD in recent years that can be compared with the existing or upcoming ...

Gauge Symmetry and Neural Networks

open access: yes, 2001
We propose a new model of neural network. It consists of spin variables to describe the state of neurons as in the Hopfield model and new gauge variables to describe the state of synapses.

Hard-thermal-loop QCD Thermodynamics

open access: yes, 2010
Naively resummed perturbative approximations to the thermodynamic functions of QCD do not converge at phenomenologically relevant temperatures. Here we review recent results of a three-loop hard-thermal-loop perturbation theory calculation of the ...

Crystal field splitting and correlation effect on the electronic structure of A2IrO3

open access: yes, 2012
The electronic structure of the honeycomb lattice iridates Na2IrO3 and Li2IrO3 has been investigated using resonant inelastic x-ray scattering (RIXS). Crystal-field split d-d excitations are resolved in the high-resolution RIXS spectra.
