Impossibility of superluminal travel in Lorentz violating theories
Antonin Coutant, Stefano Finazzi, Stefano Liberati +1
Warp drives are space-times allowing for superluminal travel. However, they are quantum mechanically unstable because they produce a Hawking-like radiation which is blue shifted at…
Black hole radiation with short distance dispersion, an analytical S-matrix approach
Antonin Coutant, Renaud Parentani, Stefano Finazzi
Local and non-local properties of Hawking radiation in the presence of short distance dispersion are computed using connection formulae. The robustness of the spectrum and that of…
Resonant Hawking radiation in Bose-Einstein condensates
Ivar Zapata, Mathias Albert, Renaud Parentani +1
We study double-barrier interfaces separating regions of asymptotically subsonic and supersonic flow of Bose condensed atoms. These setups contain at least one black hole sonic hor…
On the robustness of acoustic black hole spectra
Stefano Finazzi, Renaud Parentani
We study the robustness of the spectrum emitted by an acoustic black hole by considering series of stationary flows that become either subsonic or supersonic, i.e. when the horizon…
