Hadron masses and baryonic scales in -QCD at finite density
Björn H. Wellegehausen, Axel Maas, Andreas Wipf +1
The QCD phase diagram at densities relevant to neutron stars remains elusive, mainly due to the fermion-sign problem. At the same time, a plethora of possible phases has been predi…
-QCD: Spectroscopy and the phase diagram at zero temperature and finite density
Lorenz von Smekal, Bjoern H. Wellegehausen, Axel Maas +1
Due to the fermion sign problem, standard lattice Monte-Carlo method for QCD fail at small temperatures and high baryon densities. -QCD, QCD with the gauge group repla…
Particle in a self-dual dyon background: hidden free nature, and exotic superconformal symmetry
Mikhail S. Plyushchay, Andreas Wipf
We show that a non-relativistic particle in a combined field of a magnetic monopole and 1/r^2 potential reveals a hidden, partially free dynamics when the strength of the central p…
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…
