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…
BRST invariant scalar and vector operators in the Higgs model
David Dudal, Duifje Maria van Egmond, Giovani Peruzzo +1
We present a set of BRST invariant composite operators in the Higgs model which exhibit an overlap with the observable scalar and vector pa…
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…
Entanglement and maximal violation of the CHSH inequality in a system of two spins j: a novel construction and further observations
Giovani Peruzzo, Silvio Paolo Sorella
We study the CHSH inequality for a system of two spin particles, for generic . The CHSH operator is constructed using a set of unitary, Hermitian operators $\left\{ A_{1},A_…
