Quark determinant in domain-like gluon fields
A. C. Kalloniatis, S. N. Nedelko
We address the computation of the determinant for the Dirac operator corresponding to a quark propagating in a background gluon field of the following type: the gauge field is cova…
On Domain-like Structures in the QCD Vacuum
A. C. Kalloniatis, S. N. Nedelko
We suggest that clusters or domains of topological charge and action density occur in the QCD vacuum as an effect of singularities in gauge fields and can simultaneously lead to co…
Field Configurations and the SU(2) Haar Measure in QCD
Harald W. Griesshammer, Alex C. Kalloniatis
We characterise a class of SU(2) gluonic field configurations in the modified axial gauge where a zero mode component vanishes at some space point but the global Haar measure remai…
Discretized Light-Cone Quantization: Solving a 1+1 dimensional field theory (QED)
Stephan Elser, Hans-Christian Pauli, Alex C. Kalloniatis
We describe the programming method for generating the spectrum of bound states for relativistic quantum field theories using the nonperturbative Hamiltonian approach of Discretized…
