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…
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…
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…
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…
A numerical analysis of Araki-Uhlmann relative entropy in Quantum Field Theory
Marcelo S. Guimaraes, Itzhak Roditi, Silvio P. Sorella +1
We numerically investigate the Araki-Uhlmann relative entropy in Quantum Field Theory, focusing on a free massive scalar field in 1+1-dimensional Minkowski spacetime. Using Tomita-…
