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…
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…
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…
Numerical approach to the Bell-Clauser-Horne-Shimony-Holt inequality in quantum field theory
Philipe De Fabritiis, Marcelo S. Guimaraes, Itzhak Roditi +1
The Bell-CHSH (Clauser-Horne-Shimony-Holt) inequality in the vacuum state of a relativistic scalar quantum field is analyzed. Using Weyl operators built with smeared fields localiz…
Bell-CHSH inequality and unitary operators
M. S. Guimaraes, I. Roditi, S. P. Sorella
Unitary operators are employed to investigate the violation of the Bell-CHSH inequality. The ensuing modifications affecting both classical and quantum bounds are elucidated. The r…
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…
