Near-Tsirelson Bell-CHSH Violations in Quantum Field Theory via Carleman and Hankel Operators

David Dudal, Ken Vandermeersch

We study Bell-Clauser-Horne-Shimony-Holt (Bell-CHSH) violations in the vacuum state of free spinor fields in $(1+1)$-dimensional Minkowski spacetime. We construct explicit smooth c…
