Quantum quenches, sonic horizons and the Hawking radiation in a class of exactly solvable models
Manuele Tettamanti, Sergio L. Cacciatori, Alberto Parola
Taking advantage of the known exact mapping of the one-dimensional Hard Core Bose (HCB) fluid onto a non-interacting spinless fermion gas, we examine in full detail a thought exper…
Analogue Hawking radiation in an exactly solvable model of BEC
A. Parola, M. Tettamanti, S. L. Cacciatori
Hawking radiation, the spontaneous emission of thermal photons from an event horizon, is one of the most intriguing and elusive predictions of field theory in curved spacetimes. A…
Numerical study of a recent black hole lasing experiment
M. Tettamanti, S. L. Cacciatori, A. Parola +1
We theoretically analyse a recent experiment reporting the observation of a self-amplifying Hawking radiation in a flowing atomic condensate [J.Steinhauer, Nature Physics, vol.10,…
