Arrival times of an atomic Bose-Einstein condensate
Pascal Naidon, Lucas Happ, Denis Boiron
The times of flight of an atomic Bose-Einstein condensate are theoretically investigated in the experimentally unexplored regime corresponding to detection close to the trap of the…
Proposal of quantum arrival-time measurement with a Bose-Einstein condensate
Pascal Naidon, Lucas Happ, Denis Boiron
This work shows how a Bose-Einstein condensate of ultracold atoms could be used to address a long-standing question in quantum theory: how much time does it take for a particle to…
Stabilization of three-body resonances to bound states in a continuum
Lucas Happ, Pascal Naidon
Three-body resonances are ubiquitous in quantum few-body physics and are characterized by a finite lifetime before decaying into continuum states of their composing subsystems. In…
Closed-channel parameters of Feshbach resonances
Pascal Naidon
This work investigates how the closed channel of a Feshbach resonance is characterised by experimental observables. Surprisingly, it is found that the two-body observables associat…
