Thick oriented and nonoriented center-vortex configurations with fractional topological charge lumps
David R. Junior, L. E. Oxman, Gustavo M. Simões
Mixed oriented and nonoriented center vortices are known to generate nontrivial topological charge. However, most previous analyses have been restricted to Abelian-projected thin c…
Study of the Emergence of a Gluon Mass Scale from Center Vortices Using a Wave-Functional Formalism
David R. Junior, Gastão Krein, Luis E. Oxman +1
Lattice simulations and theoretical analyses consistently identify center vortices and monopoles as key nonperturbative configurations in Yang-Mills theory. In the continuum, the e…
Flux tube formation and the Weingarten representation of center vortices and chains
David R. Junior, Luis E. Oxman
We review some recent results regarding the formulation of mixed ensembles of oriented and nonoriented center vortices based on the Weingarten representation for the sum over surfa…
Structure of center-vortex matter in SU(4) Yang-Mills theory
Jackson A. Mickley, Derek B. Leinweber, Luis E. Oxman
The structure of center vortices is studied in SU(4) Yang-Mills theory for the first time to illuminate the interplay between elementary (center charge ) and doubly charged…
Ensembles of center vortices and chains: Insights from a natural lattice framework
D. R. Junior, L. E. Oxman
A scenario to understand the asymptotic properties of confinement between quark probes, based on a 4D mixed ensemble of percolating center-vortex worldsurfaces and chains, was init…
