Geometric Rényi mutual information induced by localized particle excitations in quantum field theory
Willy A. Izquierdo, David R. Junior, Gastão Krein
Quantum field theory exhibits rich spatial correlation structures even in the vacuum, where entanglement entropy between regions scales with the area of their shared boundary. Whil…
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…
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…
Prospecting effective Yang-Mills-Higgs models for the asymptotic confining flux tube
David R. Junior, Luis E. Oxman, Gustavo M. Simões
In this work, we analyze a large class of effective Yang-Mills-Higgs models constructed in terms of adjoint scalars. In particular, we reproduce asymptotic properties of the confin…
The infrared Yang-Mills wave functional due to percolating center vortices
D. R. Junior, L. E. Oxman, H. Reinhardt
Inspired by the center-vortex dominance in the infrared sector of Yang-Mills theory observed on the lattice, we propose a vacuum wave functional localized on an ensemble of…
Renormalizability of a first principles Yang-Mills center-vortex ensemble
D. Fiorentini, D. R. Junior, L. E. Oxman +1
Recently, a new procedure to quantize the Yang-Mills theory in the nonperturbative regime was proposed. The idea is to divide the configuration space into sectors…
From center-vortex ensembles to the confining flux tube
D. R. Junior, L. E. Oxman, G. M. Simões
In this review, we discuss the present status of the description of confining flux tubes in SU(N) pure Yang-Mills theory in terms of ensembles of percolating center vortices. This…
Study of Gribov Copies in the Yang-Mills ensemble
D. Fiorentini, D. R. Junior, L. E. Oxman +2
Recently, based on a new procedure to quantize the theory in the continuum, it was argued that Singer's theorem points towards the existence of a Yang-Mills ensemble. In the new ap…
BPS strings and the stability of the asymptotic Casimir law in adjoint flavor-symmetric YMH models
D. R. Junior, L. E. Oxman, G. M. Simões
We investigate an effective flavor-symmetric Yang-Mills-Higgs model with adjoint scalar fields. We find a set of BPS equations that provide vortex solutions and calculate t…
Renormalizability of the center-vortex free sector of Yang-Mills theory
D. Fiorentini, D. R. Junior, L. E. Oxman +1
In this work, we analyzed a recent proposal to detect continuum Yang-Mills sectors labeled by center vortices, inspired by Laplacian-type center gauges in the lattice. Init…
3D Yang-Mills confining properties from a non-Abelian ensemble perspective
D. R. Junior, L. E. Oxman, G. M. Simões
In this work, we propose a ensemble measure for center-vortex worldlines and chains equipped with non-Abelian degrees of freedom. We derive an effective field description for…
Quantum effects due to a moving Dirichlet point
C. D. Fosco, D. R. Junior, L. E. Oxman
We study quantum effects induced by a point-like object that imposes Dirichlet boundary conditions along its world-line, on a real scalar field in 1, 2 and 3 spatial dimensions…
Geometry of the Shannon mutual information in continuum QFT
David R. Junior, Luis E. Oxman
We analyze geometric terms and scaling properties of the Shannon mutual information in the continuum. This is done for a free massless scalar field theory in -dimensions, in a c…
