The staggered domain wall fermion method
A different lattice fermion method is introduced. Staggered domain wall fermions are defined in 2n + 1 dimensions and describe 2 flavors of light lattice fermions with exact U(1)×U(1) chiral symmetry in 2n dimensions. As the size of the extra dimension becomes large, 2 chiral flavors with the same chiral charge are expected to be localized on each boundary and the full SU(2n)×SU(2n) flavor chir...
متن کاملPropagator of the lattice domain wall fermion and the staggered fermion
We calculate the propagator of the domain wall fermion (DWF) of the RBC/UKQCD collaboration with 2+1 dynamical flavors of 163 × 32× 16 lattice in Coulomb gauge, by applying the conjugate gradient method. We find that the fluctuation of the propagator is small when the momenta are taken along the diagonal of the 4-dimensional lattice. Restricting momenta in this momentum region, which is called ...
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 کاملInteracting staggered domain wall fermions
I remember it very clearly: It was a sunny spring Northern California afternoon in 1988. I had just passed my Ph.D. exams and was about to start research. My Ph.D. advisor took his other student (also my collaborator) and me out to lunch to the place across from the physics department. This was unusual, so it naturally weighed a lot. I do not remember his exact words, but he basically told us a...
متن کاملDomain wall fermion zero modes on classical
The domain wall approach to lattice fermions employs an additional dimension, in which gauge fields are merely replicated, to separate the chiral components of a Dirac fermion. It is known that in the limit of infinite separation in this new dimension, domain wall fermions have exact zero modes, even for gauge fields which are not smooth. We explore the effects of finite extent in the fifth dim...
