Gravitational quantum friction and the information-loss problem
Francesco Del Porro, Francesco Di Filippo
We study the gravitational collapse of a shell, modeled as a coherent state of quantum matter. Without adding any physics beyond semiclassical gravity, we show that the universal g…
Semiclassical regularity of compact trapped regions: From dynamical horizons to inner extremality
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +1
In eternal black-hole spacetimes, inner horizons are Cauchy horizons and are generically unstable. For non-extremal inner horizons, this includes both the classical mass-inflation…
Macroscopic backreaction of the trace anomaly on classical vacuum backgrounds
Raúl Carballo-Rubio, Francesco Di Filippo, Shinji Mukohyama +1
We study the backreaction of quantum fields in the Boulware vacuum state on the Schwarzschild geometry, using the Riegert--Mottola--Vaulin renormalized stress-energy tensor derived…
Imprints of quantum vacuum fluctuations on the gravitational field of a spherical mass
Raúl Carballo-Rubio, Francesco Di Filippo, Shinji Mukohyama +1
The Schwarzschild geometry, describing the gravitational field of a spherical mass in classical vacuum, is one of the most famous vacuum solutions of the Einstein field equations.…
Can light-rings self-gravitate?
Francesco Di Filippo, Luciano Rezzolla
In a spherically symmetric and static spacetime of a compact object, such as that of a Schwarzschild black hole, the light-ring is a 2-sphere where photons experience the only poss…
Fully extremal black holes: a black hole graveyard?
Francesco Di Filippo, Stefano Liberati, Matt Visser
While the standard point of view is that the ultimate endpoint of black hole evolution is determined by Hawking evaporation, there is a growing evidence that classical and semi-cla…
