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…
