Comparing geometric and gravitational particle production in Jordan and Einstein frames
Alessio Belfiglio, Orlando Luongo, Tommaso Mengoni
We explore cosmological particle production associated with inflationary fluctuations by comparing gravitational and geometric mechanisms, within a non-minimal Yukawa-like coupling…
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…
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…
