Many-body dark solitons in one-dimensional hard-core Bose gases
Manuele Tettamanti, Alberto Parola
The existence and stability of solitonic states in one-dimensional repulsive Bose-Einstein condensates is investigated within a fully many-body framework by considering the limit o…
On the role of interactions in trans-sonically flowing atomic condensates
Manuele Tettamanti, Iacopo Carusotto, Alberto Parola
We provide a joint numerical-analytical study of the physics of a flowing atomic Bose-Einstein condensate in the combined presence of an external trap and a step potential which ac…
Formation dynamics of black- and white-hole horizons in an analogue gravity model
Manuele Tettamanti, Alberto Parola
We investigate the formation dynamics of sonic horizons in a Bose gas confined in a (quasi) one-dimensional trap. This system is one of the most promising realizations of the analo…
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,…
