[HTML][HTML] Genuine tripartite nonlocality and entanglement in curved spacetime
SM Wu, HS Zeng - The European Physical Journal C, 2022 - Springer
We study the genuine tripartite nonlocality (GTN) and the genuine tripartite entanglement
(GTE) of Dirac fields in the background of a Schwarzschild black hole. We find that the …

Optimal quantum estimation of the Unruh-Hawking effect
We address on general quantum-statistical grounds the problem of optimal detection of the
Unruh-Hawking effect. We show that the effect signatures are magnified up to potentially …
