Breakdown of the mean field for dark solitons of dipolar bosons in a one-dimensional harmonic trap
Michał Kowalski, Rafał Ołdziejewski, Kazimierz Rzążewski
We directly compare the mean-field and the many-body approach in a one-dimensional Bose system in a harmonic trap. Both contact and dipolar interactions are considered. We propose…
Strongly correlated quantum droplets in quasi-1D dipolar Bose gas
Rafał Ołdziejewski, Wojciech Górecki, Krzysztof Pawłowski +1
We exploit a few- to many-body approach to study strongly interacting dipolar bosons in the quasi-one-dimensional system. The dipoles attract each other while the short range inter…
Dark solitons revealed in Lieb-Liniger eigenstates
Weronika Golletz, Wojciech Górecki, Rafał Ołdziejewski +1
We study how dark solitons, i.e. solutions of one-dimensional single-particle nonlinear time-dependent Schrödinger equation, emerge from eigenstates of a linear many-body model of…
Diagnosing a two-body state of ultracold atoms with light
Rafał Ołdziejewski, Kazimierz Rzążewski
An absorption of a weak pulse by two identical atoms moving in a trap is investigated. Based on atom-light interactions we present a microscopic model of a two-body wave function d…
