dc.description.abstractA new method for computing all elements of the lattice quark propagator is proposed. The method combines the spectral decomposition of the propagator, computing the lowest eigenmodes exactly, with noisy estimators which are ‘diluted’, i.e. taken to have support only on a subset of time, space, spin or color. We find that the errors are dramatically reduced compared to traditional noisy estimator techniquesen
