Gravitational redshift of broadband relativistic quantum photons
Alessio Lapponi, Alessandro Ferreri, David Edward Bruschi +1
Gravitational redshift is a key prediction of general relativity that has been experimentally verified. Nevertheless, its existence in the context of relativistic and quantum physi…
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…
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…
Relativistic quantum communication between harmonic oscillator detectors
Alessio Lapponi, Dimitris Moustos, David Edward Bruschi +1
We propose a model of communication employing two harmonic oscillator detectors interacting through a scalar field in a background Minkowski spacetime. In this way, the scalar fiel…
Modeling black hole evaporative mass evolution via radiation from moving mirrors
Michael R. R. Good, Alessio Lapponi, Orlando Luongo +1
We investigate the evaporation of an uncharged and non-rotating black hole (BH) in vacuum, by taking into account the effects given by the shrinking of the horizon area. These incl…
Black hole thermodynamics from logotropic fluids
Salvatore Capozziello, Rocco D'Agostino, Alessio Lapponi +1
We show that the Einstein field equations with a negative cosmological constant can admit black hole solutions whose thermodynamics coincides with that of logotropic fluids, recent…
Quantum communication through a partially reflecting accelerating mirror
Michael R. R. Good, Alessio Lapponi, Orlando Luongo +1
Motivated by the fact that the null-shell of a collapsing black hole can be described by a perfectly reflecting accelerating mirror, we investigate an extension of this model to mi…
