摘要

本文介绍了自旋 1 Unruh-De Witt 探测器与相对论标量量子场相互作用的研究。在追踪出场模式之后,我们利用所得到的二方量子系统密度矩阵来研究贝尔-CHSH 不等式的违反情况。在自旋 1/2 的情况下,量子场的效应会导致违反大小的减小,而在自旋 1 的情况下,违反大小可能同时减小或增大。这种效应归因于齐里尔逊约束在自旋 1 的情况下没有饱和。

A Study of Spin 1 Unruh–De Witt Detectors
A study of the interaction of spin 1 Unruh–De Witt detectors with a relativistic scalar quantum field is presented here. After tracing out the field modes, the resulting density matrix for a bipartite qutrit system is employed to investigate the violation of the Bell–CHSH inequality. Unlike the case of spin 1/2, for which the effects of the quantum field result in a decrease in the size of violation, in the case of spin 1, both a decrease or an increase in the size of the violation may occur. This effect is ascribed to the fact that Tsirelson’s bound is not saturated in the case of qutrits.
