Causal structure in spin-foams
Eugenio Bianchi, Pierre Martin-Dussaud
The metric field of general relativity is almost fully determined by its causal structure. Yet, in spin-foam models for quantum gravity, the role played by the causal structure is…
The End of a Black Hole's Evaporation -- Part II
Farshid Soltani, Carlo Rovelli, Pierre Martin-Dussaud
We derive an explicit expression for the transition amplitude from black to white hole horizon at the end of Hawking evaporation using covariant loop quantum gravity.
Asymptotics of coherent invariant tensors
Pietro Dona, Marco Fanizza, Pierre Martin-Dussaud +1
We study the semiclassical limit of a class of invariant tensors for infinite-dimensional unitary representations of of the principal series, correspond…
Black-to-White Hole Scenario: Foundation and Evaporation
Pierre Martin-Dussaud
A theory of quantum gravity is expected to change profoundly our understanding of black holes. Quantum theory has already shown, as a first approximation, that a black hole slowly…
The End of a Black Hole's Evaporation -- Part I
Fabio D'Ambrosio, Marios Christodoulou, Pierre Martin-Dussaud +2
At the end of Hawking evaporation, the horizon of a black hole enters a physical region where quantum gravity cannot be neglected. The physics of this region has not been much expl…
An experiment to test the discreteness of time
Marios Christodoulou, Andrea Di Biagio, Pierre Martin-Dussaud
Time at the Planck scale () is an unexplored physical regime. It is widely believed that probing Planck time will remain for long an impossible task. Yet…
Evaporating black-to-white hole
Pierre Martin-Dussaud, Carlo Rovelli
We construct and discuss the form of the (effective) spacetime geometry inside a black hole undergoing a quantum transition to a white hole, taking into account the back-reaction o…
Interior metric and ray-tracing map in the firework black-to-white hole transition
Carlo Rovelli, Pierre Martin-Dussaud
The possibility that a black hole could tunnel into a white hole has recently received attention. Here we present a metric that improves the 'firework' metric: it describes the ent…
