Gribov horizon under the (lattice) microscope
Jeff Greensite, Stefan Olejnik, Daniel Zwanziger
TL;DR
This paper investigates the Gribov horizon in Coulomb gauge, demonstrating that the enhancement of near-zero Faddeev-Popov modes is linked to percolating center vortex configurations through numerical simulations.
Contribution
It provides numerical evidence connecting the Gribov horizon's properties to vortex configurations, advancing understanding of confinement mechanisms in gauge theories.
Findings
Enhanced near-zero Faddeev-Popov modes confirmed numerically
Percolating center vortices are associated with the Gribov horizon
Link between vortex configurations and Coulomb energy established
Abstract
The infinite color-Coulomb energy of color-charged states is related to enhanced density of near-zero modes of the Faddeev-Popov operator in Coulomb gauge. We confirm the enhancement in numerical simulations and show that it is tied to the presence of percolating center vortex configurations.
