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…
The Status of Horava Gravity
M. Herrero-Valea
Horava gravity is a proposal for a UV completion of gravitation obtained by endowing the space-time manifold with a preferred foliation in space-like hypersurfaces. This allows for…
Well-posed evolution of field theories with anisotropic scaling: the Lifshitz scalar field in a black hole space-time
Marcelo E. Rubio, Áron D. Kovács, M. Herrero-Valea +2
Partial differential equations exhibiting an anisotropic scaling between space and time -- such as those of Horava-Lifshitz gravity -- have a dispersive nature. They contain higher…
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…
