Semiclassical spacetimes at super-Planckian scales from delocalized sources
Ali Akil, Mariano Cadoni, Leonardo Modesto +2
We derive the gravitational field and the spacetime metric generated by sources in quantum superposition of different locations. We start by working in a Newtonian approximation, i…

Superradiance in deformed Kerr black holes
Mauro Oi, Edgardo Franzin, Stefano Liberati
Ongoing observations in the strong-field regime are in optimal agreement with general relativity, although current errors still leave room for small deviations from Einstein's theo…

Superradiance in Kerr-like black holes
Edgardo Franzin, Stefano Liberati, Mauro Oi
Recent strong-field regime tests of gravity are so far in agreement with general relativity. In particular, astrophysical black holes appear all to be consistent with the Kerr spac…
