Three-outcome multipartite Bell inequalities: applications to dimension witnessing and spin-nematic squeezing in many-body systems

G Müller-Rigat, A Aloy, M Lewenstein, M Fadel… - arXiv preprint arXiv …, 2024 - arxiv.org
We present a three-outcome permutationally-invariant Bell inequality, which we show to be
naturally suited to explore nonlocal correlations in many-body spin-1 systems or SU (3) …
