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…
Perturbative approach to the infrared gluon propagator in the maximal Abelian gauge
D. M. van Egmond, L. C. Ferreira, A. D. Pereira +2
The inclusion of a mass-like term for the gluon in Yang-Mills theories quantized in the Landau gauge has proven to be an effective way of reproducing lattice results for gauge-fixe…
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…
