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…
Probing Mermin's inequalities violations through pseudospin operators
Philipe De Fabritiis, Itzhak Roditi, Silvio P. Sorella
The violation of Mermin's inequalities is analyzed by making use of two different Bell setups built with pseudospin operators. Employing entangled states defined by means of squeez…
Entangled coherent states and violations of Bell-CHSH inequalities
Philipe De Fabritiis, Fillipe M. Guedes, Giovani Peruzzo +1
Three classes of entangled coherent states are employed to study the Bell-CHSH inequality. By using pseudospin operators in infinite dimensional Hilbert spaces, four dichotomic ope…
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…
