Staggered Fermion, its Symmetry and Ichimatsu-Patterned Lattice
arXiv:hep-lat/0411037 · doi:10.1016/j.nuclphysbps.2004.11.155
Abstract
We investigate exact symmetries of a staggered fermion in D dimensions. The Dirac operator is reformulated by SO(2D) Clifford algebra. The chiral symmetry, rotational invariance and parity symmetries are clarified in any dimension. Local scalar and pseudo-scalar modes are definitely determined, in which we find non-standard modes. The relation to Ichimatsu-patterned lattice approach is discussed.
