Bosonization, vertex operators and maximal violation of the Bell-CHSH inequality in wedge regions
arXiv:2604.18513
Abstract
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.
