Fate of gravitational collapse in semiclassical gravity
Carlos Barcelo, Stefano Liberati, Sebastiano Sonego +1
While the outcome of gravitational collapse in classical general relativity is unquestionably a black hole, up to now no full and complete semiclassical description of black hole f…
New constraints on Planck-scale Lorentz Violation in QED from the Crab Nebula
Luca Maccione, Stefano Liberati, Annalisa Celotti +1
We set constraints on O(E/M) Lorentz Violation in QED in an effective field theory framework. A major consequence of such assumptions is the modification of the dispersion relation…
Quantum gravity phenomenology via Lorentz violations
S. Liberati
The search for a quantum theory of gravity has been one of the main aims of theoretical physics for many years by now. However the efforts in this direction have been often hampere…
Reply to "Can gravitational dynamics be obtained by diffeomorphism invariance of action?"
Thomas P. Sotiriou, Stefano Liberati
In a previous work we showed that, in a suitable setting, one can use diffeomorphism invariance in order to derive gravitational field equations from boundary terms of the gravitat…
