The Casimir effect in Gribov-Zwanziger theory
David Dudal, Philipe De Fabritiis, Sebbe Stouten +1
We consider Yang-Mills theory with two infinite parallel plates, separated by a distance \(L\), that are perfect magnetic conductors (PMC) or perfect electric conductors (PEC). Rec…
Charting the different phases of Yang-Mills-Chern-Simons-Higgs theories
Daniel O. R. Azevedo, Gustavo P. de Brito, Philipe De Fabritiis +1
We explore Yang-Mills-Chern-Simons theories coupled to a Higgs-like field in the fundamental representation of quantized in linear covariant gauges in three Euclidean dimen…
Numerical approach to the Bell-Clauser-Horne-Shimony-Holt inequality in quantum field theory
Philipe De Fabritiis, Marcelo S. Guimaraes, Itzhak Roditi +1
The Bell-CHSH (Clauser-Horne-Shimony-Holt) inequality in the vacuum state of a relativistic scalar quantum field is analyzed. Using Weyl operators built with smeared fields localiz…
Four-gluon vertex from the Curci-Ferrari model at one-loop order
Nahuel Barrios, Philipe De Fabritiis, Marcela Peláez
We compute the four-gluon vertex from the Curci-Ferrari model at one-loop order for a collinear configuration. Our results display a good agreement with the first lattice data for…
Using Weyl operators to study Mermin's inequalities in Quantum Field Theory
Philipe De Fabritiis, Fillipe M. Guedes, Marcelo S. Guimaraes +2
Mermin's inequalities are investigated in a Quantum Field Theory framework by using von Neumann algebras built with Weyl operators. We devise a general construction based on the To…
Weyl operators, Tomita-Takesaki theory, and Bell-Clauser-Horne-Shimony-Holt inequality violations
P. De Fabritiis, F. M. Guedes, M. S. Guimaraes +3
The violation of the Bell-CHSH inequality in the vacuum state of a relativistic free real scalar field is established by means of the Tomita-Takesaki construction and of the direct…
Maximal violation of the Bell-Clauser-Horne-Shimony-Holt inequality via bumpified Haar wavelets
David Dudal, Philipe De Fabritiis, Marcelo S. Guimaraes +2
We devise a general setup to investigate the violation of the Bell-CHSH inequality in the vacuum state in the context of Quantum Field Theory. We test the method with massless spin…
BRST invariant formulation of the Bell-CHSH inequality in gauge field theories
David Dudal, Philipe De Fabritiis, Marcelo S. Guimaraes +2
A study of the Bell-CHSH inequality in gauge field theories is presented. By using the Kugo-Ojima analysis of the BRST charge cohomology in Fock space, the Bell-CHSH inequality is…
Mermin's inequalities in Quantum Field Theory
Philipe De Fabritiis, Itzhak Roditi, Silvio Paolo Sorella
A relativistic Quantum Field Theory framework is devised for Mermin's inequalities. By employing smeared Dirac spinor fields, we are able to introduce unitary operators which creat…
Refined Gribov-Zwanziger theory coupled to scalar fields in the Landau gauge
Gustavo P. de Brito, Philipe De Fabritiis, Antonio D. Pereira
The Refined Gribov-Zwanziger (RGZ) action in the Landau gauge accounts for the existence of infinitesimal Gribov copies as well as the dynamical formation of condensates in the inf…
Self-dual Maxwell-Chern-Simons solitons in a parity-invariant scenario
W. B. De Lima, P. De Fabritiis
We present a self-dual parity-invariant Maxwell-Chern-Simons scalar . We show that the energy functional admits a Bogomol'nyi-type lower bound, who…
Vortices in a parity-invariant Maxwell-Chern-Simons model
W. B. De Lima, P. De Fabritiis
In this work we propose a parity-invariant Maxwell-Chern-Simons model coupled with two charged scalar fields in dimensions, and show that it admits finite-…
