Universal Horizons without Hypersurface Orthogonality

Francesco Del Porro, Stefano Liberati, Jacopo Mazza

A key consequence of Lorentz-violating gravity is the emergence of modified dispersion relations implying the absence of a universal maximum propagation speed. This challenges the…

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…

Threshold configurations in the presence of Lorentz violating dispersion relations

D. Mattingly, T. Jacobson, S. Liberati

A general characterization of lower and upper threshold configurations for two particle reactions is determined under the assumptions that the single particle dispersion relations…

Threshold effects and Planck scale Lorentz violation: combined constraints from high energy astrophysics

T. Jacobson, S. Liberati, D. Mattingly

Recent work has shown that dispersion relations with Planck scale Lorentz violation can produce observable effects at energies many orders of magnitude below the Planck energy M. T…
