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…

Quantum entanglement in cosmology

Alessio Belfiglio, Orlando Luongo, Stefano Mancini

We discuss recent progress in the study of entanglement within cosmological frameworks, focusing on both momentum and position-space approaches and also reviewing the possibility t…

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-…

How cosmological expansion affects communication between distant quantum systems

Alessio Lapponi, Orlando Luongo, Stefano Mancini

A quantum communication protocol between harmonic oscillator detectors, interacting with a quantum field, is developed in a cosmological expanding background. The aim is to see if…

Horizon entanglement area law from regular black hole thermodynamics

Alessio Belfiglio, S. Mahesh Chandran, Orlando Luongo +1

We investigate the thermodynamics of regular black hole configurations via quantum analogs of entropy and energy -- namely, the entanglement entropy and entanglement energy -- near…

Preserving quantum information in cosmology

Salvatore Capozziello, Alessio Lapponi, Orlando Luongo +1

The effects of cosmological expansion on quantum bosonic states are investigated, using quantum information theory. In particular, a generic Bogoliubov transformation of bosonic fi…

Making two particle detectors in flat spacetime communicate quantumly

Alessio Lapponi, Jorma Louko, Stefano Mancini

A communication protocol with non-zero quantum capacity is found when the two communicating parts are particle detector models in (3+1)-dimensional spacetime. In particular, as det…

Entanglement entropy in quantum black holes

Alessio Belfiglio, Orlando Luongo, Stefano Mancini +1

We discuss the entanglement entropy for a massive Klein-Gordon field in two Schwarzschild-like quantum black hole spacetimes, also including a nonminimal coupling term with the bac…

Geometric and topological corrections to Schwarzschild black hole

Rocco D'Agostino, Orlando Luongo, Stefano Mancini

In this paper, we compute departures in the black hole thermodynamics induced by either geometric or topological corrections to general relativity. Specifically, we analyze the sph…

Superhorizon entanglement from inflationary particle production

Alessio Belfiglio, Orlando Luongo, Stefano Mancini

We investigate entanglement generation between the sub- and super-Hubble modes of inflaton fluctuations, in the context of particle production from perturbations during inflation.…

Self gravity decoheres quantum systems

Alessio Lapponi, Stefano Mancini, Frank K. Wilhelm +1

We study the effects of self gravity on the quantum state of a massive and static particle that initially contains quantum coherence between two positions. We employ linearized qua…
