Classical U(1) Lattice Gauge Theory in D=2
H. Gausterer, M. Sammer
Under the hypothesis of no topological structure below a certain scale, we prove that any U(1) lattice configuration corresponds to a classical U(1) gauge field with zero local fie…
Strong Coupling Lattice Schwinger Model on Large Spherelike Lattices
H. Gausterer, C. B. Lang
The lattice regularized Schwinger model for one fermion flavor and in the strong coupling limit is studied through its equivalent representation as a restricted 8-vertex model. The…
Lee-Yang zeroes in the one flavour massive lattice Schwinger model
H. Gausterer, C. B. Lang
We study the partition function of the model formulated with Wilson fermions with only one species, both analytically and numerically. At strong coupling we construct the solution…
On the Correct Convergence of Complex Langevin Simulations for Polynomial Actions
H. Gausterer
There are problems in physics and particularly in field theory which are defined by complex valued weight functions where is a polynomial action $S: R^n \rightarrow C…
On the Phase Structure of the Schwinger Model with Wilson Fermions
H. Gausterer, C. B. Lang
We study the phase structure of the massive one flavour lattice Schwinger model on the basis of the finite size scaling behaviour of the partition function zeroes. At we obs…
The Mechanism of Complex Langevin Simulations
H. Gausterer, Sean Lee
We discuss conditions under which expectation values computed from a complex Langevin process will converge to integral averages over a given complex valued weight function. Th…
