Searching for Bell-CHSH-Violating Bose Operators
The study sought exact local observables in relativistic Bose fields that exhibit maximal Bell correlations. The authors constructed an operator-realization method by classifying exact Cliffordizations of the Bose quadrature, leading to a quadratic assignment problem for translation-cell involutions. This yielded an exact finite-band correlation functional and confirmed wedge locality for the free-field CCR construction.
