MCRG Flow for the nonlinear Sigma Model
Daniel Koerner, Bjoern H. Wellegehausen, Andreas Wipf
A study of the renormalization group flow in the three-dimensional nonlinear O(N) sigma model using Monte Carlo Renormalization Group (MCRG) techniques is presented. To achieve thi…

Finetuning the continuum limit in low-dimensional supersymmetric theories
Bjoern H. Wellegehausen, Daniel Koerner, Andreas Wipf
Supersymmetry is a prominent candidate for physics beyond the standard model. In order to compute the spectrum of supersymmetric theories, we employ nonperturbative lattice QFT tec…
