Superfield BRST Charge and the Master Action
M. Grigoriev, P. H. Damgaard
Using a superfield formulation of extended phase space, we propose a new form of the Hamiltonian action functional. A remarkable feature of this construction is that it directly le…
Spectral Sum Rules of the Dirac operator and Partially Quenched Chiral Condensates
P. H. Damgaard, K. Splittorff
Exploiting Virasoro constraints on the effective finite-volume partition function, we derive generalized Leutwyler-Smilga spectral sum rules of the Dirac operator to high order. By…
Looking for Effects of Topology in the Dirac Spectrum of Staggered Fermions
P. H. Damgaard, U. M. Heller, R. Niclasen +1
We classify SU(3) gauge field configurations in different topological sectors by the smearing technique. In each sector we compute the distribution of low lying eigenvalues of the…
Finite-Volume Scaling of the Quenched Chiral Condensate
P. H. Damgaard, R. G. Edwards, U. M. Heller +1
In the large-volume limit with the mass-dependent chiral condensate is predicted to satisfy exact finite-volume scaling laws that fall into three major…
Universal Scaling of the Chiral Condensate in Finite-Volume Gauge Theories
P. H. Damgaard, R. G. Edwards, U. M. Heller +1
We confront exact analytical predictions for the finite-volume scaling of the chiral condensate with data from quenched lattice gauge theory simulations. Using staggered fermions i…
Staggered Fermions and Gauge Field Topology
P. H. Damgaard, U. M. Heller, R. Niclasen +1
Based on a large number of smearing steps, we classify SU(3) gauge field configurations in different topological sectors. For each sector we compare the exact analytical prediction…
