Zero density heavy quark SU(2) gauge theory and the Stefan-Boltzmann limit
Kurt Langfeld, Norbert Lages, Hugo Reinhardt
SU(2) lattice gauge theory is investigated where the traces of the Wilson lines at any lattice point and along each direction is constrained to zero. Hence, each of the lattice con…
The Gluon Propagator in Lattice Landau Gauge with twisted boundary conditions
Torsten Tok, Kurt Langfeld, Hugo Reinhardt +1
We investigate the infrared behaviour of the gluon propagator in Landau gauge on a lattice with twisted boundary conditions. Analytic calculations using Dyson-Schwinger equations,…
Topologically non-trivial field configurations - interplay of vortices and Dirac eigenmodes
Stefan Solbrig, Jochen Gattnar, Christof Gattringer +4
Gluon field configurations with non-trivial topology like instantons, magnetic monopoles and center vortices play a crucial role in QCD and, in particular, for the spontaneous brea…
A novel improved action for SU(3) lattice gauge theory
Kurt Langfeld
SU(3) lattice gauge theory is studied by means of an improved action where a Wilson loop is supplemented to the standard plaquette term. By contrast to earlier studies…
Worldline Approach To The Casimir Effect
L. Moyaerts, K. Langfeld, H. Gies
We present a new method to compute quantum energies in presence of a background field. The method is based on the string-inspired worldline approach to quantum field theory and its…
