Description

By interpreting species doublers as members of the same supermultiplet we describe the N=2 supersymmetric quantum mechanichs (including interaction) on a lattice with both supersymmetries exactly realized. Supersymmetric Ward identities are satisfies and the continuum limit is smooth. Interaction is non-local on the lattice, but locality is recovered in the continuum limit.
