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…
Bell and Mermin inequalities in Quantum Field Theory from vacuum projectors and Weyl operators
M. S. Guimaraes, I. Roditi, S. P. Sorella +1
The use of the vacuum projector and of the unitary Weyl operators enables us to construct a set of Hermitian dichotomic operators in relativistic scalar Qu…
Investigation of the Bell-CHSH inequality in diamond regions
M. S. Guimaraes, I. Roditi, S. P. Sorella
A numerical setup for the Bell-CHSH inequality for causal diamonds in Minkowski spacetime is presented. Upon choosing a suitable set of test functions supported in the diamon…
Quantum-classical correspondence of a system of interacting bosons in a triple-well potential
E. R. Castro, Jorge Chavez-Carlos, I. Roditi +2
We study the quantum-classical correspondence of an experimentally accessible system of interacting bosons in a tilted triple-well potential. With the semiclassical analysis, we ge…
