A dual order parameter from fundamentally colour charged matter
Markus Hopfer, Mario Mitter, Bernd-Jochen Schaefer +1
The center phase transition of QCD and of fundamentally charged scalar QCD at non-vanishing temperature is investigated within a Dyson-Schwinger approach. The temperature dependenc…
On the analytic structure of scalar glueball operators at Born level
Andreas Windisch, Markus Q. Huber, Reinhard Alkofer
We study the analytic structure of the two-point function of the operator F2 which is expected to describe a scalar glueball. The calculation of the involved integrals is complicat…
Optimizing the pulse shape for Schwinger pair production
Christian Kohlfürst, Mario Mitter, Gregory von Winckel +2
Recent studies of the dynamically assisted Schwinger effect have shown that particle production is significantly enhanced by a proper choice of the electric field. We demonstrate t…
Towards a self-consistent solution of the Landau gauge quark-gluon vertex Dyson-Schwinger equation
Andreas Windisch, Markus Hopfer, Reinhard Alkofer
The quark-gluon vertex in Landau gauge QCD is investigated in the Dyson-Schwinger approach. The aim is to obtain a fully self-consistent solution of the quark propagator and the qu…
Baryon properties from the covariant Faddeev equation
Helios Sanchis-Alepuz, Reinhard Alkofer, Richard Williams
A calculation of the masses and electromagnetic properties of the Delta and Omega baryon together with their evolution with the current quark mass is presented. Hereby a generalize…
Solving the Ghost-Gluon System of Yang-Mills Theory on GPUs
Markus Hopfer, Reinhard Alkofer, Gundolf Haase
We solve the ghost-gluon system of Yang-Mills theory using Graphics Processing Units (GPUs). Working in Landau gauge, we use the Dyson-Schwinger formalism for the mathematical desc…
