Uncovering Low-Dimensional Topological Structure in the QCD Vacuum
I. Horvath, S. J. Dong, T. Draper +5
Recently, we have pointed out that sign-coherent 4-dimensional structures can not dominate topological charge fluctuations in QCD vacuum at all scales. Here we show that an enhance…
Low Energy Chiral Lagrangian Parameters for Scalar and Pseudoscalar Mesons
W. Bardeen, E. Eichten, H. Thacker
We present results of a high-statistics study of scalar and pseudoscalar meson propagators in quenched QCD at two values of lattice spacing, beta = 5.7 and 5.9, with clover-improve…
Topological Charge Correlators, Spectral Bounds, and Contact Terms
H. Thacker, S. J. Dong, T. Draper +4
The structure of topological charge fluctuations in the QCD vacuum is strongly restricted by the spectral negativity of the Euclidean 2-point correlator for and the prese…
The local structure of topological charge fluctuations in QCD
I. Horvath, S. J. Dong, T. Draper +4
We introduce the Dirac eigenmode filtering of topological charge density associated with Ginsparg-Wilson fermions as a tool to investigate the local structure of topological charge…
On the Local Structure of Topological Charge Fluctuations in QCD
I. Horvath, S. J. Dong, T. Draper +4
We consider the lattice topological charge density introduced by Hasenfratz, Laliena and Niedermayer and propose its eigenmode expansion as a tool to investigate the structure of t…
Local Chirality of Low-Lying Dirac Eigenmodes and the Instanton Liquid Model
I. Horvath, S. J. Dong, T. Draper +6
The reasons for using low-lying Dirac eigenmodes to probe the local structure of topological charge fluctuations in QCD are discussed, and it is pointed out that the qualitative do…
