Domain-Wall Fermions at Strong Coupling
The DWF formulation becomes increasingly problematic at gauge couplings for which a < 2 GeV, where the roughness of the gauge field leads to increased explicit chiral symmetry breaking (mres). This problem becomes especially severe for sufficiently strong coupling where the underlying 4-dimensional Wilson theory is in the Aoki phase. We review our attempts to find a suitable modification of the...
متن کاملStaggered Domain Wall Fermions
Staggered Domain Wall Fermions (SDWF) combine the attractive chiral properties of staggered fermions with those of domain wall fermions. SDWF describe four flavors with exact U(1)×U(1) flavor chiral symmetry. An extra lattice dimension is introduced and the full SU(4)×SU(4) flavor chiral symmetry is recovered as its size is increased. Here, the free theory of SDWF is described and a preliminary...
متن کاملOptimal domain-wall fermions
I show that the conventional formulations of lattice domain-wall fermion with any finite Ns (in the fifth dimension) do not preserve the chiral symmetry optimally and propose a new action which preserves the chiral symmetry optimally for any finite Ns. PACS numbers: 11.15.Ha, 11.30.Rd, 12.38.Gc
متن کاملGap Domain Wall Fermions
I demonstrate that the chiral properties of Domain Wall Fermions (DWF) in the large to intermediate lattice spacing regime of QCD, 1 to 2 GeV, are significantly improved by adding to the action two standard Wilson fermions with supercritical mass equal to the negative DWF five dimensional mass. Using quenched DWF simulations I show that the eigenvalue spectrum of the transfer matrix Hamiltonian...
متن کاملWarped Domain Wall Fermions
We consider Kaplan’s domain wall fermions in the presence of an Anti-de Sitter (AdS) background in the extra dimension. Just as in the flat space case, in a completely vector-like gauge theory defined after discretizing this extra dimension, the spectrum contains a very light charged fermion whose chiral components are localized at the ends of the extra dimensional interval. The component on th...
