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…
Mass Dependence of Araki Relative Entropy through Modular Theory
M. S. Guimaraes, I. Roditi, S. P. Sorella
Building on the established one-particle formula for the Araki relative entropy of coherent states, we study how its value acquires a nontrivial dependence on the mass of the scala…
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 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…
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…
Squeezed states for Frenkel-like two-fermion composite bosons
Francisco Figueiredo, Itzhak Roditi
We investigate squeezed states of composite bosons (cobosons) formed by pairs of spin- fermions, with emphasis on Frenkel-like cobosons. While squeezing for standard bosonic m…
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…
