Mechanics of non-Killing horizons
Francesco Del Porro, Jacopo Mazza
We investigate the mechanics of stationary axisymmetric non-Killing horizons, which emerge in spacetimes that do not enjoy the symmetry known as circularity -- as is commonly the c…
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…
Gravity in dimensions and realizations of the diffeomorphisms group
Riccardo Martini, Alessandro Ugolotti, Francesco Del Porro +1
We discuss two distinct realizations of the diffeomorphism group for metric gravity, which give rise to theories that are classically equivalent, but quantum mechanically distinct.…
