The intention of these notes is to outline how we construct the overlap operator in the gwu-qcd framework. The overlap operator preserves chiral symmetry on the lattice, and is the most ideal operator used to explore low pion masses. The massless overlap is defined by

\(\mathbf{D_0} = \rho(1+\gamma_5)\epsilon(H)\)

Given a vector \(\vec{\eta}\), we want to compute the solution \(\vec{x}\), which is the matrix vector multiplication

\(\mathbf{D_0} \vec{\eta} = \vec{x} \)
