Comment on "Fractional topological charges and the lowest Dirac modes"
Derar Altarawneh, Roman Höllwieser
We comment on a recent article published in Phys. Rev. D98 (2018) no.9, 094513, arXiv:1811.09029, pointing out severe problems in the numerical investigation leading to questionabl…
A model of random center vortex lines in continuous 2+1-dimensional space-time
Derar Altarawneh, Michael Engelhardt, Roman Höllwieser
A picture of confinement in QCD based on a condensate of thick vortices with fluxes in the center of the gauge group (center vortices) is studied. Previous concrete model realizati…
Center Vortices, Area Law and the Catenary Solution
Roman Höllwieser, Derar Altarawneh
We present meson-meson (Wilson loop) correlators in Z(2) center vortex models for the infrared sector of Yang-Mills theory, i.e., a hypercubic lattice model of random vortex surfac…
Confining Bond Rearrangement in the Random Center Vortex Model
Derar Altarawneh, Roman Höllwieser, Michael Engelhardt
We present static meson-meson and baryon--anti-baryon potentials in Z(2) and Z(3) random center vortex models for the infrared sector of Yang-Mills theory, i.e., hypercubic lattice…
Random center vortex lines in continuous 3D space-time
Roman Höllwieser, Derar Altarawneh, Michael Engelhardt
We present a model of center vortices, represented by closed random lines in continuous 2+1- dimensional space- time. These random lines are modeled as being piece-wise linear and…
