The Schwinger Model with Perfect Staggered Fermions
W. Bietenholz, H. Dilger
We construct and test a quasi-perfect lattice action for staggered fermions. The construction starts from free fermions, where we suggest a new blocking scheme, which leads to exce…
The Schwinger Model with Perfect Staggered Fermions
W. Bietenholz, H. Dilger
We construct a new perfect action for free staggered fermions, which is more local than the one obtained from the standard block average scheme. This pays off in superior propertie…
Truncated Perfect Actions for Staggered Fermions
W. Bietenholz, H. Dilger
We discuss the behavior of free perfect staggered fermions and truncated versions thereof. The study includes flavor non-degenerate masses. We suggest a new blocking scheme, which…
The perfect action for non-degenerate staggered fermions
H. Dilger
The perfect action of free staggered fermions is calculated by blocking from the continuum for degenerate and non-degenerate flavor masses. The symmetry structure, connecting flavo…
Topological transitions in the euclidean 2d U(1)-Higgs model
Hermann Dilger
The two-dimensional U(1)-gauged Higgs model is studied on an euclidean lattice of size , where the temperature is of the order of the sphaleron mass. Th…
Scaling in the two-dimensional U(1)--Higgs model
Hermann Dilger, Jochen Heitger
We study the continuum limit of the U(1)--Higgs model with variable scalar field length, which is qualitatively different from the fixed length case. Our simulations concentra…
Topological Zero Modes in Monte Carlo Simulations
H. Dilger
We present an improvement of global Metropolis updating steps, the instanton hits, used in a hybrid Monte Carlo simulation of the two-flavor Schwinger model with staggered fermions…
How well do lattice simulations reproduce the different aspects of the geometric Schwinger model
H. Dilger, H. Joos
We compare continuum and lattice formulation of the geometric Schwinger Model on the torus. The lattice reproduces the anomaly, related to non-trivial topological gauge co…
