Numerical Investigation of the 2D N=2 Wess-Zumino Model
Christian Wozar, Georg Bergner, Tobias Kaestner +2
We study lattice formulations of the two-dimensional N=2 Wess-Zumino model with a cubic superpotential. Discretizations with and without lattice supersymmetries are compared. We ob…
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…
Supersymmetric lattice models in one and two dimensions
Tobias Kaestner, Georg Bergner, Sebastian Uhlmann +2
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…
Z_3 Polyakov Loop Models and Inverse Monte-Carlo Methods
Christian Wozar, Tobias Kaestner, Sebastian Uhlmann +2
We study effective Polyakov loop models for SU(3) Yang-Mills theory at finite temperature. A comprehensive mean field analysis of the phase diagram is carried out and compared to t…
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…
Ward Identities for Invariant Group Integrals
S. Uhlmann, R. Meinel, A. Wipf
We derive two types of Ward identities for the generating functions for invariant integrals of monomials of the fundamental characters for arbitrary simple compact Lie groups. The…
