Topological Charge Evolution in the Markov-Chain of QCD
Derek B. Leinweber, Anthony G. Williams, Jian-bo Zhang +1
The topological charge is studied on lattices of large physical volume and fine lattice spacing. We illustrate how a parity transformation on the SU(3) link-variables of lattice ga…
An Algorithm for Obtaining Reliable Priors for Constrained-Curve Fits
Terrence Draper, Shao-Jing Dong, Ivan Horvath +3
We introduce the ``Sequential Empirical Bayes Method'', an adaptive constrained-curve fitting procedure for extracting reliable priors. These are then used in standard augmented-ch…
Low-dimensional long-range topological structure in the QCD vacuum
I. Horvath, S. J. Dong, T. Draper +5
Lattice topological charge associated with Ginsparg-Wilson fermions exhibits generic topological stability over quantum ensemble of configurations contributing to the QCD path inte…
Chiral Logs in Quenched QCD
Y. Chen, S. J. Dong, T. Draper +5
The quenched chiral logs are examined on a lattice with Iwasaki gauge action and overlap fermions. The pion decay constant is used to set the lattice spacing…
Low-Dimensional Long-Range Topological Charge Structure in the QCD Vacuum
I. Horvath, S. J. Dong, T. Draper +5
While sign-coherent 4-dimensional structures cannot dominate topological charge fluctuations in the QCD vacuum at all scales due to reflection positivity, it is possible that enhan…
