Fast evaluation and locality of overlap fermions

High Energy Physics - Lattice 2015-06-25 v1

Abstract

In order to construct improved overlap fermions, we start from a short ranged approximate Ginsparg-Wilson fermion and insert it into the overlap formula. We show that its polynomial evaluation is accelerated considerably compared to the standard Neuberger fermion. In addition the degree of locality is strongly improved.
