Finite Weyl polynomials and the approach to Tsirelson's bound in relativistic scalar quantum field theory
J. G. A. Caribé, M. S. Guimaraes, I. Roditi +1
We construct four bounded Hermitian operators, each one a finite polynomial in the unitary Weyl operators, for the Bell-CHSH inequality in a free massive scalar field in dime…
More on Majorana fields, modular localization and near saturation of the Tsirelson bound
J. R. Apfata, J. G. A. Caribé, S. P. Sorella
The authors study the Bell‑CHSH inequality for a free massless Majorana field in 1+1 dimensions and show, via modular wedge localization, that the Tsirelson bound is nearly saturat…
Modular Theory and the Bell-CHSH inequality in relativistic scalar Quantum Field Theory
J. G. A. Caribé, M. S. Guimaraes, I. Roditi +1
The Tomita-Takesaki modular theory is employed to discuss the Bell-CHSH inequality in wedge regions. By using the Bisognano-Wichmann results, the construction of a set of wedge loc…
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…
Bosonization, vertex operators and maximal violation of the Bell-CHSH inequality in wedge regions
J. G. A. Caribé, M. S. Guimaraes, I. Roditi +1
It is pointed out that the vertex operators of a chiral boson in 1+1 dimensions provide an explicit realization of dichotomic, bounded, Hermitian operators that saturate the Tsirel…
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 -…
