Genuine tripartite nonlocality and entanglement in curved spacetime

Abstract We study the genuine tripartite nonlocality (GTN) and entanglement (GTE) of Dirac fields in background a Schwarzschild black hole. find that Hawking radiation degrades both physically accessible GTN GTE. The former suffers from “sudden death” at some critical temperature, latter approaches to nonzero asymptotic value limit infinite temperature. also effect cannot generate inaccessible GTN, but can GTE for fermion curved spacetime. These results show on one hand pass through event horizon hole, do can, other surviving generated fermions spacetime are all not nonlocal. Some monogamy relations between found.
