Description
We discuss taste-splitting mass terms and their symmetries in the 3+1 dimensional staggered fermion system, and show that the one-link mass term in the x-direction preserves the largest symmetry. Using this mass term, we construct a 2+1 dimensional boundary theory and demonstrate that the flavor SU(2) symmetry and parity anomaly of the boundary theory are reproduced by the conserved charges generating the Onsager algebra on the 3+1 dimensional bulk lattice.
