A bstract The interaction between Unruh-De Witt spin 1/2 detectors and a real scalar field is scrutinized by making use of the Tomita-Takesaki modular theory as applied to Von Neumann algebra Weyl operators. enables evaluate in an exact way trace over quantum degrees freedom. resulting density matrix employed study Bell-CHSH correlator. It turns out that, consequence with field, violation inequality exhibits decreasing compared case which absent.
