Journal ArticleDOI
Novel quark-field creation operator construction for hadronic physics in lattice QCD
Mike Peardon,John Bulava,Justin Foley,Colin Morningstar,Jozef J. Dudek,Robert G. Edwards,Bálint Joó,Huey-Wen Lin,David G. Richards,Keisuke Jimmy Juge +9 more
TL;DR: In this article, a low-rank operator is used to define smooth fields that are to be used in hadron creation operators, and the resulting space of smooth fields is small enough that all elements of the reduced quark propagator can be computed exactly at reasonable computational cost.
Journal ArticleDOI
Practical all-to-all propagators for lattice QCD
TL;DR: The method combines the spectral decomposition of the propagator, computing the lowest eigenmodes exactly, with noisy estimators which are ‘diluted’, i.e. taken to have support only on a subset of time, space, spin or color.
Journal ArticleDOI
First results from 2+1 dynamical quark flavors on an anisotropic lattice: Light-hadron spectroscopy and setting the strange-quark mass
Huey-Wen Lin,Saul D. Cohen,Jozef J. Dudek,Robert Edwards,Bálint Joó,David G. Richards,John Bulava,Justin Foley,Colin Morningstar,Eric Engelson,Stephen J. Wallace,K. Jimmy Juge,Nilmani Mathur,Mike Peardon,Sinead M. Ryan +14 more
TL;DR: In this paper, the first light-hadron spectroscopy on a set of dynamical, anisotropic lattices was presented, and a convenient set of coordinates that parameterize the two-dimensional plane of light and strange-quark masses was introduced.
Journal ArticleDOI
Improved stochastic estimation of quark propagation with Laplacian Heaviside smearing in lattice QCD
Colin Morningstar,John Bulava,Justin Foley,Keisuke Jimmy Juge,David Lenkner,Mike Peardon,Chik Him Wong +6 more
TL;DR: In this article, a method of stochastically estimating the low-lying effects of quark propagation is proposed which allows accurate determinations of temporal correlations of single-hadron and multihop operators in lattice QCD.
Journal ArticleDOI
Excited State Nucleon Spectrum with Two Flavors of Dynamical Fermions
John Bulava,Robert Edwards,Eric Engelson,Justin Foley,Balint Joo,Adam Lichtl,Huey-Wen Lin,Nilmani Mathur,Colin Morningstar,David G. Richards,Stephen J. Wallace +10 more
TL;DR: In this paper, a large number of baryon operators were developed on lattice QCD with two flavors of dynamical quarks and the lowest four energies were reported in each of the six irreducible representations.
