Accelerated overlap fermions

Numerical evaluation of the overlap Dirac operator is difficult since it contains the sign function ε(H w ) of the Hermitian Wilson-Dirac operator H w with a negative mass term. The problems are due to H w having very small eigenvalues on the equilibrium background configurations generated in c...
