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…
A study of the spin 1 Unruh-De Witt detectors
F. M. Guedes, M. S. Guimaraes, I. Roditi +1
A study of the spin 1 Unruh-De Witt detectors interacting with a relativistic scalar quantum field is presented. After tracing out the field modes, the resulting density matrix for…
Unruh-De Witt detectors, Bell-CHSH inequality and Tomita-Takesaki theory
Fillipe M. Guedes, Marcelo S. Guimaraes, Itzhak Roditi +1
The interaction between Unruh-De Witt spin detectors and a real scalar field is scrutinized by making use of the Tomita-Takesaki modular theory as applied to the Von Neumann…
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…
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…
