Dissipative processes at the acoustic horizon
Maria Luisa Chiofalo, Dario Grasso, Massimo Mannarelli +1
A transonic fluid flow generates an acoustic hole that is the hydrodynamic analogue of a gravitational black hole. Acoustic holes emit a detectable thermal radiation of phonons at…
Phonon emission by acoustic black holes
Massimo Mannarelli, Dario Grasso, Silvia Trabucco +1
We present a novel interpretation of the Hawking temperature of acoustic holes, the hydrodynamic analogue of standard black holes, by connecting the geometrical properties of the h…
Hawking temperature and phonon emission in acoustic holes
Massimo Mannarelli, Dario Grasso, Silvia Trabucco +1
Acoustic holes are the hydrodynamic analogue of standard black holes. Featuring an acoustic horizon, these systems spontaneously emit phonons at the Hawking temperature. We derive…
AEDGE: Atomic Experiment for Dark Matter and Gravity Exploration in Space
Yousef Abou El-Neaj, Cristiano Alpigiani, Sana Amairi-Pyka +129
We propose in this White Paper a concept for a space experiment using cold atoms to search for ultra-light dark matter, and to detect gravitational waves in the frequency range bet…
