Cooling for instantons and the Wrath of Nahm
S. Bilson-Thompson, F. D. R. Bonnet, D. B. Leinweber +1
The dynamics of instantons and anti-instantons in lattice QCD can be studied by analysing the action and topological charge of configurations as they approach a self-dual or anti-s…
Numerical study of lattice index theorem usingimproved cooling and overlap fermions
J. B. Zhang, S. O. Bilson-Thompson, F. D. R. Bonnet +3
We investigate topological charge and the index theorem on finite lattices numerically. Using mean field improved gauge field configurations we calculate the topological charge Q u…
Hadron Masses From Novel Fat-Link Fermion Actions
J. M. Zanotti, S. Bilson-Thompson, F. D. R. Bonnet +6
The hadron mass spectrum is calculated in lattice QCD using a novel fat-link clover fermion action in which only the irrelevant operators in the fermion action are constructed usin…
Gluons, quarks, and the transition from nonperturbative to perturbative QCD
Anthony G. Williams, Frederic D. R. Bonnet, Patrick O. Bowman +3
Lattice-based investigations of two fundamental QCD quantities are described, namely the gluon and quark propagators in Landau gauge. We have studied the Landau gauge gluon propaga…
Improved Smoothing Algorithms for Lattice Gauge Theory
Frederic D. R. Bonnet, Derek B. Leinweber, Anthony G. Williams +1
The relative smoothing rates of various gauge field smoothing algorithms are investigated on -improved $\suthree$ Yang--Mills gauge field configurations. In particul…
Infinite Volume and Continuum Limits of the Landau-Gauge Gluon Propagator
F. D. R. Bonnet, P. O. Bowman, D. B. Leinweber +2
We extend a previous improved action study of the Landau gauge gluon propagator, by using a variety of lattices with spacings from to 0.41 fm, to more fully explore fini…
