New chiral lattice actions of the Borici-Creutz type
arXiv:1311.5664 · doi:10.1103/PhysRevD.89.074508
Abstract
We generalize the Borici-Creutz action in such a way that the position of the second zero and the direction which breaks the hypercubic symmetry can be arbitrarily chosen, and the action has still the correct continuum limit. Minimal doubling is guaranteed if the distance between the two zeros does not become too large. Special values of this distance could turn out to be particularly convenient for efficient numerical simulations of minimally doubled fermions.
