Entanglement degradation in regular and singular spacetimes
Orlando Luongo, Stefano Mancini, Sebastiano Tomasi
We study entanglement degradation near the horizons of regular, Reissner-Nordström, and Schwarzschild-de Sitter black holes, considering the Bardeen, Hayward, and generalized Haywa…

Entanglement entropy evolution during gravitational collapse
Alessio Belfiglio, Orlando Luongo, Stefano Mancini +1
We investigate the dynamics of the ground state entanglement entropy for a discretized scalar field propagating within the Oppenheimer-Snyder collapse metric. Starting from a well-…
