报告题目：Three-outcome Bell inequalities tailored to SU3 many-body systems报 告 人：Guillem Müller Rigat (ICFO)报告时间：2025年7月1日10：00报告地点：物理楼W260报告简介：We present a three-outcome Bell inequality which we show to be naturally suited to explore non-local correlations in many-body spin-1 systems or SU(3) models. From such an inequality, we show how simple bounds on single-particl...
