The removal of critical slowing down
M. A. Clark, J. Brannick, R. C. Brower +4
We present promising initial results of our adaptive multigrid solver developed for application directly to the non-Hermitian Wilson-Dirac system in 4 dimensions, as opposed to the…
Adaptive Multigrid Algorithm for the QCD Dirac-Wilson Operator
J. Brannick, R. C. Brower, M. A. Clark +2
We present a new multigrid solver that is suitable for the Dirac operator in the presence of disordered gauge fields. The key behind the success of the algorithm is an adaptive pro…
Fermions on tori in uniform abelian fields
L. Giusti, A. Gonzalez-Arroyo, Ch. Hoelbling +2
We study Fermi fields defined on tori in the presence of gauge backgrounds carrying non-trivial topology. We show that 2k dimensional field space can alternatively be described by…
A Study of the 't Hooft Model with the Overlap Dirac Operator
F. Berruto, L. Giusti, C. Hoelbling +1
We present the results of an exploratory numerical study of two dimensional QCD with overlap fermions. We have performed extensive simulations for U(N_c) and SU(N_c) color groups w…
Free energy of an SU(2) monopole-antimonopole pair
Ch. Hoelbling, C. Rebbi, V. A. Rubakov
We present a high-statistic numerical study of the free energy of a monopole-antimonopole pair in pure SU(2) theory. We find that the monopole-antimonopole interaction potential ex…
Periodic Instantons in SU(2) Yang-Mills-Higgs Theory
G. Bonini, S. Habib, E. Mottola +3
The properties of periodic instanton solutions of the classical SU(2) gauge theory with a Higgs doublet field are described analytically at low energies, and found numerically for…
