Effective lattice theories for Polyakov loops
Leander Dittmann, Thomas Heinzl, Andreas Wipf
We derive effective actions for SU(2) Polyakov loops using inverse Monte Carlo techniques. In a first approach, we determine the effective couplings by requiring that the effective…

Effective sigma models and lattice Ward identities
Leander Dittmann, Thomas Heinzl, Andreas Wipf
We perform a lattice analysis of the Faddeev-Niemi effective action conjectured to describe the low-energy sector of SU(2) Yang-Mills theory. To this end we generate an ensemble of…
