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…
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…
Sticky physics of joy: On the dissolution of spherical candies
Andreas Windisch, Herbert Windisch, Anita Popescu
Assuming a constant mass-decrease per unit-surface and -time we provide a very simplistic model for the dissolution process of spherical candies. The aim is to investigate the quan…
Examining the Analytic Structure of Green's Functions: Massive Parallel Complex Integration using GPUs
Andreas Windisch, Reinhard Alkofer, Gundolf Haase +1
Graphics Processing Units (GPUs) are employed for a numerical determination of the analytic structure of two-point correlation functions of Quantum Field Theories. These functions…
