Massive Domain Wall Fermions on Four-dimensional Anisotropic Lattices
We formulate the massive domain wall fermions on anisotropic lattices.
For the massive domain wall fermion, we find that the dispersion relation
assumes the usual form in the low momentum region when the bare parameters are
properly tuned. The quark self-energy and the quark field renormalization
constants are calculated to one-loop in bare lattice perturbation theory. For
light domain wall fermions, we verified that the chiral mode is stable against
quantum fluctuations on anisotropic lattices. This calculation serves as a
guidance for the tuning of the parameters in the quark action in future
numerical simulations.Comment: 36 pages, 14 figures, references adde
