On the influence of three-point functions on the propagators of Landau gauge Yang-Mills theory
Markus Q. Huber, Lorenz von Smekal
We solve the Dyson-Schwinger equations of the ghost and gluon propagators of Landau gauge Yang-Mills theory together with that of the ghost-gluon vertex. The latter plays a central…
Universal Aspects of QCD-like Theories
Lorenz von Smekal
In these lectures I review some basic examples of how the concepts of universality and scaling can be used to study aspects of the chiral and the deconfinement transition, if not i…
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…
Fractional electric charge and quark confinement
Sam R. Edwards, André Sternbeck, Lorenz von Smekal
Owing to their fractional electric charges, quarks are blind to transformations that combine a color center phase with an appropriate electromagnetic one. Such transformations are…
An improved formalism for the Grover search algorithm
James M. Chappell, M. A. Lohe, Lorenz von Smekal +2
The Grover search algorithm is one of the two key algorithms in the field of quantum computing, and hence it is of significant interest to describe it in the most efficient mathema…
