On a class of bounded Hermitian operators for the Bell-CHSH inequality in Quantum Field Theory
M. S. Guimaraes, I. Roditi, S. P. Sorella
The violation of the Bell-CHSH inequality in a relativistic scalar Quantum Field Theory is analysed by means of a set of bounded Hermitian operators constructed out of the unitary…
Bell and Mermin inequalities in Quantum Field Theory from vacuum projectors and Weyl operators
M. S. Guimaraes, I. Roditi, S. P. Sorella +1
The use of the vacuum projector and of the unitary Weyl operators enables us to construct a set of Hermitian dichotomic operators in relativistic scalar Qu…
Bell-CHSH inequality and unitary transformations in Quantum Field Theory
D. O. R. Azevedo, F. M. Guedes, M. S. Guimaraes +3
Unitary transformations are employed to enhance the violations of the Bell-CHSH inequality in relativistic Quantum Field Theory. The case of the scalar field in Minkowski spa…
Investigation of the Bell-CHSH inequality in diamond regions
M. S. Guimaraes, I. Roditi, S. P. Sorella
A numerical setup for the Bell-CHSH inequality for causal diamonds in Minkowski spacetime is presented. Upon choosing a suitable set of test functions supported in the diamon…
Bell's inequality in relativistic Quantum Field Theory
M. S. Guimaraes, I. Roditi, S. P. Sorella
A concise and self-contained introduction to the Bell inequality in relativistic Quantum Field Theory is presented. Taking the example of a real scalar massive field, the violation…
Gluing together Quantum Field Theory and Quantum Mechanics: a look at the Bell-CHSH inequality
M. S. Guimaraes, I. Roditi, S. P. Sorella
The Bell-CHSH inequality in the vacuum state of a relativistic scalar quantum field is revisited by making use of the Hilbert space , where ${\cal H…
