Modular wedge localization, Majorana fields and the Tsirelson limit of the Bell-CHSH inequality
J. G. A. Caribé, M. S. Guimaraes, I. Roditi +1
The massive Majorana field in dimension is employed to investigate the violation of the Bell-CHSH inequality in relativistic Quantum Field Theory. We give an explicit rapidit…
Cat states and violation of the Bell-CHSH inequality in relativistic Quantum Field Theory
M. S. Guimaraes, I. Roditi, S. P. Sorella
A cat state localized in the right Rindler wedge is employed to study the violation of the Bell-CHSH inequality in a relativistic scalar free Quantum Field Theory. By means of the…
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…
Mass Dependence of the Araki-Uhlmann Relative Entropy Across Dimensions
João G. A. Caribé, Marcelo S. Guimarães, Itzhak Roditi +2
We investigate the mass dependence of the Araki-Uhlmann relative entropy between a localized coherent excitation and the vacuum state of a free scalar quantum field on the -…
Investigating the Araki-Uhlmann relative entropy between two coherent states in relativistic Quantum Field Theory
João G. A. Caribé, Marcelo S. Guimaraes, Itzhak Roditi +1
A numerical setup for investigating the Araki-Uhlmann relative entropy between two coherent states is presented for a scalar massive Quantum Field Theory in ()-dimensional Min…
Relative entropy of single-mode squeezed states in Quantum Field Theory
Marcelo S. Guimaraes, Itzhak Roditi, Silvio P. Sorella +1
Utilizing the Tomita-Takesaki modular theory, we derive a closed-form analytic expression for the Araki-Uhlmann relative entropy between a single-mode squeezed state and the vacuum…
