Description
It's a well-known fact that Lorentz Violating (LV) theories of gravity, such as Horava-Lifshitz gravity, highlight possibility of a renormalizable, non-Lorentz-invariant UV completion of General Relativity (GR).
On the phenomenological side, the breaking of Local Lorentz Invariance gives a different notion of causality, for which the LV-Black Hole solutions assume a different internal structure with respect to GR.
Surprisingly, if one studies the behaviour of quantum fields on top of this geometries, one discovers that LV-BHs still radiate by Hawking effect.
In this talk, I will present how the different notion of causality in these theories affects Hawking radiation and how this could possibly lead to observable LV signatures.
