Bosonization, vertex operators and maximal violation of the Bell-CHSH inequality in wedge regions

It is pointed out that the vertex operators of a chiral boson in 1+1 dimensions provide an explicit realization of dichotomic, bounded, Hermitian operators that saturate the Tsirelson bound of the Bell-CHSH inequality in the vacuum state. --- Source: arXiv:2604.18513v1 - http://arxiv.org/abs/2604.18513v1 PDF: https://arxiv.org/pdf/2604.18513v1 Original Link: http://arxiv.org/abs/2604.18513v1
