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…
The phase diagram of a gauge theory with fermionic baryons
Axel Maas, Lorenz von Smekal, Björn Wellegehausen +1
The fermion-sign problem at finite density is a persisting challenge for Monte-Carlo simulations. Theories that do not have a sign problem can provide valuable guidance and insight…
Casimir Scaling and String Breaking in G(2) Gluodynamics
Bjoern H. Wellegehausen, Andreas Wipf, Christian Wozar
We study the potential energy between static charges in G(2) gluodynamics in three and four dimensions. Our work is based on an efficient local hybrid Monte-Carlo algorithm and a m…
