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 Hayw…

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-…

Linear and nonlinear clusterings of Horndeski-inspired dark energy models with fast transition
Orlando Luongo, Francesco Pace, Sebastiano Tomasi
We analyze time-dependent dark energy equations of state through linear and nonlinear structure formation and their quintessence potentials, characterized by fast, recent transitio…
