Non-Local effective SU(2) Polyakov-loop models from inverse Monte-Carlo methods
Bardiya Bahrampour, Björn Wellegehausen, Lorenz von Smekal
The strong-coupling expansion of the lattice gauge action leads to Polyakov-loop models that effectively describe gluodynamics at low temperatures, and together with the hopping ex…
Spectroscopy of two dimensional N=2 Super Yang Mills theory
Daniel August, Björn Wellegehausen, Andreas Wipf
Albeit the standard model is the most successful model of particles physics, it still has some theoretical shortcomings, for instance the hierarchy problem, the absence of dark mat…
Four-Fermion Theories with Exact Chiral Symmetry in Three Dimensions
Daniel Schmidt, Björn Wellegehausen, Andreas Wipf
We investigate a class of four-fermion theories which includes well-known models like the Gross-Neveu model and the Thirring model. In three spacetime dimensions, they are used to…
