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…
Tunneling method for Hawking quanta in analogue gravity
Francesco Del Porro, Stefano Liberati, Marc Schneider
Analogue Hawking radiation from acoustic horizons is now a well-established phenomenon, both theoretically and experimentally. Its persistence, despite the modified dispersion rela…
Rescuing the Unruh Effect in Lorentz Violating Gravity
F. Del Porro, M. Herrero-Valea, S. Liberati +1
While the robustness of Hawking radiation in the presence of UV Lorentz breaking is well-established, the Unruh effect has posed a challenge, with a large literature concluding tha…
Hawking Radiation in Lorentz Violating Gravity: A Tale of Two Horizons
F. Del Porro, M. Herrero-Valea, S. Liberati +1
Since their proposal, Lorentz violating theories of gravity have posed a potential threat to black hole thermodynamics, as superluminal signals appeared to be incompatible with the…
On the Resilience of Black Hole Evaporation: Gravitational Tunneling through Universal Horizons
M. Schneider, F. Del Porro, M. Herrero-Valea +1
Using a quantum tunneling derivation, we show the resilience of Hawking radiation in Lorentz violating gravity. In particular, we show that the standard derivation of the Hawking e…
Gravitational Tunneling in Lorentz Violating Gravity
F. Del Porro, M. Herrero-Valea, S. Liberati +1
Black holes in Lorentz violating gravity, such as Einstein--Aether or Horava--Lifshitz Gravity, are drastically different from their general relativistic siblings. Although they al…
Time Orientability and Particle Production from Universal Horizons
Francesco Del Porro, Mario Herrero-Valea, Stefano Liberati +1
We discuss particle production in spacetimes endowed with a universal horizon in Einstein--Aether and Horava gravity. We argue that continuity and differentiability of the lapse fu…
