On topological properties of vacuum defects in lattice Yang-Mills theories

A. V. Kovalenko, S. M. Morozov, M. I. Polikarpov +1

We study correlations between low-lying modes of the overlap Dirac operator and vacuum defects, center vortices and three-dimensional volumes, in lattice SU(2) gluodynamics. The lo…

Towards SU(2) invariant formulation of the monopole confinement mechanism

Katsuya Ishiguro, Yoshihiro Mori, Yoshifumi Nakamura +5

The type of the vacuum is studied numerically in the maximally Abelian (MA) gauge and in the Landau (LA) gauge of SU(2) gluodynamics. The type of the vacuum is determined by a rati…

Vacuum type of SU(2) gluodynamics in maximally Abelian and Landau gauges

M. N. Chernodub, Katsuya Ishiguro, Yoshihiro Mori +5

The vacuum type of SU(2) gluodynamics is studied using Monte-Carlo simulations in maximally Abelian (MA) gauge and in Landau (LA) gauge, where the dual Meissner effect is observed…

Quark helicity flip generalized parton distributions from two-flavor lattice QCD

M. Gockeler, Ph. Hagler, R. Horsley +5

We present an initiatory study of quark helicity flip generalized parton distributions (GPDs) in n_f=2 lattice QCD, based on clover-improved Wilson fermions for a large number of c…

Investigation of the Second Moment of the Nucleon's g1 and g2 Structure Functions in Two-Flavor Lattice QCD

M. Göckeler, R. Horsley, D. Pleiter +5

The reduced matrix elements a_2 and d_2 are computed in lattice QCD with N_f=2 flavors of light dynamical (sea) quarks. For proton and neutron targets we obtain as our best estimat…

Evidence for fine tuning of fermionic modes in lattice gluodynamics

F. V. Gubarev, S. M. Morozov, M. I. Polikarpov +1

We consider properties of zero and near-zero fermionic modes in lattice gluodynamics. The modes are known to be sensitive to the topology of the underlying gluonic fields in the qu…

Perturbation theory for O(3) topological charge correlators

Miguel Aguado, Erhard Seiler

To check the consistency of positivity requirements for the two-point correlation function of the topological charge density, which were identified in a previous paper, we are comp…

Localized eigenmodes of covariant Laplacians in the Yang-Mills vacuum

J. Greensite, S. Olejnik, M. I. Polikarpov +2

As a probe of the Yang-Mills vacuum, we study numerically the eigenmode spectrum of the covariant lattice Laplacian operator. We find that the eigenmodes at the low and high ends o…

The clash of positivities in topological density correlators

Miguel Aguado, Erhard Seiler

We discuss the apparent conflict between reflection positivity and positivity of the topological susceptibility in two-dimensional nonlinear sigma models and in four-dimensional ga…
