Between quantum and classical gravity: Is there a mesoscopic spacetime?
Eolo Di Casola, Stefano Liberati, Sebastiano Sonego
Between the microscopic domain ruled by quantum gravity, and the macroscopic scales described by general relativity, there might be an intermediate, "mesoscopic" regime, where spac…
Weak equivalence principle for self-gravitating bodies: A sieve for purely metric theories of gravity
Eolo Di Casola, Stefano Liberati, Sebastiano Sonego
We propose the almost-geodesic motion of self-gravitating test bodies as a possible selection rule among metric theories of gravity. Starting from a heuristic statement, the "gravi…
Nonequivalence of equivalence principles
Eolo Di Casola, Stefano Liberati, Sebastiano Sonego
Equivalence principles played a central role in the development of general relativity. Furthermore, they have provided operative procedures for testing the validity of general rela…
Qualitative study of perfect-fluid Friedmann-Lema\^ıtre-Robertson-Walker models with a cosmological constant
Sebastiano Sonego, Vittorino Talamini
The evolution of spatially homogeneous and isotropic cosmological models containing a perfect fluid with equation of state p=wρ and a cosmological constant Λ is investigated for ar…
Minimal conditions for the existence of a Hawking-like flux
Carlos Barcelo, Stefano Liberati, Sebastiano Sonego +1
We investigate the minimal conditions that an asymptotically flat general relativistic spacetime must satisfy in order for a Hawking-like Planckian flux of particles to arrive at f…
Hawking-like radiation from evolving black holes and compact horizonless objects
Carlos Barcelo, Stefano Liberati, Sebastiano Sonego +1
Usually, Hawking radiation is derived assuming (i) that a future eternal event horizon forms, and (ii) that the subsequent exterior geometry is static. However, one may be interest…
