Two-Dimensional Wess-Zumino Models at Intermediate Couplings
Tobias Kaestner, Georg Bergner, Sebastian Uhlmann +2
We consider the two-dimensional N=(2,2) Wess-Zumino model with a cubic superpotential at weak and intermediate couplings. Refined algorithms allow for the extraction of reliable ma…
Relation between chiral symmetry breaking and confinement in YM-theories
Franziska Synatschke, Andreas Wipf, Kurt Langfeld
Spectral sums of the Dirac-Wilson operator and their relation to the Polyakov loop are thoroughly investigated. The approach by Gattringer is generalized to mode sums which reconst…
Low-dimensional Supersymmetric Lattice Models
Georg Bergner, Tobias Kaestner, Sebastian Uhlmann +1
We study and simulate N=2 supersymmetric Wess-Zumino models in one and two dimensions. For any choice of the lattice derivative, the theories can be made manifestly supersymmetric…
Inverse Monte-Carlo determination of effective lattice models for SU(3) Yang-Mills theory at finite temperature
Christian Wozar, Tobias Kaestner, Andreas Wipf +1
This paper concludes our efforts in describing SU(3)-Yang-Mills theories at different couplings/temperatures in terms of effective Polyakov-loop models. The associated effective co…
Spectral sums of the Dirac-Wilson Operator and their relation to the Polyakov loop
Franziska Synatschke, Andreas Wipf, Christian Wozar
We investigate and compute spectral sums of the Wilson lattice Dirac operator for quenched SU(3) gauge theory. It is demonstrated that there exist sums which serve as order paramet…
Generalized Potts-Models and their Relevance for Gauge Theories
Andreas Wipf, Thomas Heinzl, Tobias Kaestner +1
We study the Polyakov loop dynamics originating from finite-temperature Yang-Mills theory. The effective actions contain center-symmetric terms involving powers of the Polyakov loo…
