Preparing for N_f=2 simulations at small lattice spacings
M. Della Morte, P. Fritzsch, B. Leder +6
We discuss some large effects of dynamical fermions. One is a cutoff effect, others concern the contribution of multi-pion states to correlation functions and are expected to survi…

Universality in the Gross-Neveu model
F. Knechtli, T. Korzec, B. Leder +1
We consider universal finite size effects in the large-N limit of the continuum Gross-Neveu model as well as in its discretized versions with Wilson and with staggered fermions. Af…

An adaptive aggregation based domain decomposition multilevel method for the lattice wilson dirac operator: multilevel results
A. Frommer, K. Kahl, S. Krieg +2
In lattice QCD computations a substantial amount of work is spent in solving linear systems arising in Wilson's discretization of the Dirac equations. We show first numerical resul…
