Abstract
We present results of the eigenvalue spectrum for the staggered Dir\"ac operator obtained using a modified Lanczos algorithm. We identify zero modes and non-zero modes. We derive the chiral Ward identity derived from the conserved symmetry, and check it numerically. This is the first step toward construction of an improved method to identify zero modes reliably with staggered fermions.
