On the consistency of the Aoki-phase
Stephen R. Sharpe
Lattice QCD with two flavors of Wilson fermions can exhibit spontaneous breaking of flavor and parity, with the resulting "Aoki phase" characterized by the non-zero expectation val…
Reply to: `Comment on: " 't Hooft vertices, partial quenching, and rooted staggered QCD" '
Claude Bernard, Maarten Golterman, Yigal Shamir +1
We reply to Creutz's comments on our paper " 't Hooft vertices, partial quenching, and rooted staggered QCD." We show that his criticisms are incorrect and result from a misunderst…
Applying the Wang-Landau Algorithm to Lattice Gauge Theory
Barak Bringoltz, Stephen R. Sharpe
We implement the Wang-Landau algorithm in the context of SU(N) lattice gauge theories. We study the quenched, reduced version of the lattice theory and calculate its density of sta…
Breakdown of large-N quenched reduction in SU(N) lattice gauge theories
Barak Bringoltz, Stephen R. Sharpe
We study the validity of the large-N equivalence between four-dimensional SU(N) lattice gauge theory and its momentum quenched version--the Quenched Eguchi-Kawai (QEK) model. We fi…
Taste symmetry breaking with HYP-smeared staggered fermions
Taegil Bae, David H. Adams, Chulwoo Jung +5
We study the impact of hypercubic (HYP) smearing on the size of taste breaking for staggered fermions, comparing to unimproved and to asqtad-improved staggered fermions. As in prev…
't Hooft vertices, partial quenching, and rooted staggered QCD
Claude Bernard, Maarten Golterman, Yigal Shamir +1
We discuss the properties of 't Hooft vertices in partially quenched and rooted versions of QCD in the continuum. These theories have a physical subspace, equivalent to ordinary QC…
