Majorana bilinears, compact modular seeds and the approach to the Tsirelson bound
M. S. Guimaraes, I. Roditi, S. P. Sorella
In this work we study the Bell-CHSH inequality in the vacuum of the free massive Majorana field in dimensions, taking as the dichotomic observables of the two parties even bi…

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…

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…
