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…
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…
Coherence and entanglement in the ground-state of a bosonic Josephson junction:from macroscopic Schrödinger cats to separable Fock states
Giovanni Mazzarella, Luca Salasnich, Alberto Parola +1
We consider a bosonic Josephson junction made of ultracold and dilute atoms confined by a quasi one-dimensional double-well potential within the two-site Bose-Hubbard model fra…
