The sum of entanglement and subsystem coherence is invariant under quantum reference frame transformations
Carlo Cepollaro, Ali Akil, PaweÅ CieÅliÅski +2
Recent work on quantum reference frames (QRFs) has demonstrated that superposition and entanglement are properties that change under QRF transformations. Given their utility in qua…
A Quantum Superposition of Black Hole Evaporation Histories: Recovering Unitarity
Ali Akil, Lorenzo Giannelli, Leonardo Modesto +3
Black hole evaporation is one of the most striking phenomena at the interface between gravity and quantum physics. In Hawking's semi-classical treatment, where matter is quantum me…
Conformalons: a new class of black hole mimickers
Leonardo Modesto, Ali Akil, Cosimo Bambi
In any conformally invariant gravitational theory, the space of exact solutions is greatly enlarged. Therefore, we cannot exclude the Weyl's conformal invariance to be spontaneousl…
Black Hole Information From Non-vacuum Localised Quantum States
Ali Akil, Riccardo Falcone, Nicetu Tibau Vidal +1
We revisit Hawking's black hole radiation derivation, including the quantum state of the initial matter forming the black hole. We investigate how non-vacuum initial quantum states…
