Diffraction induced quantum chaos in a one-dimensional Bose gas
M. Olshanii, G. Aupetit-Diallo, S. G. Jackson +2
We investigate the Lieb--Liniger model of interacting one-dimensional bosons coupled to a localized impurity, modeled by a delta barrier. While the Lieb--Liniger gas is integrable,…
Exact Solution for Two -Interacting Bosons on a Ring in the Presence of a -Barrier: Asymmetric Bethe Ansatz for Spatially Odd States
Maxim Olshanii, Mathias Albert, Gianni Aupetit-Diallo +2
In this article, we apply the recently proposed Asymmetric Bethe Ansatz method to the problem of two one-dimensional, short-range-interacting bosons on a ring in the presence of a…
Expansion of one-dimensional spinor gases from power-law traps
Ovidiu I. Patu, Gianni Aupetit-Diallo
Free expansion following the removal of axial confinement represents a fundamental nonequilibrium scenario in the study of many-body ultracold gases. Using the stationary phase app…
Interaction induced Anderson transition in a kicked one dimensional Bose gas
Hazel Olsen, Pierre Devillard, Gianni Aupetit-Diallo +2
We investigate the Lieb-Liniger model of one-dimensional bosons subjected to periodic kicks. In both the non-interacting and strongly interacting limits, the system undergoes dynam…
Accuracy of time-dependent GGE under weak dissipation
Luca Lumia, Gianni Aupetit-Diallo, Jérôme Dubail +1
Unitary integrable models typically relax to a stationary Generalized Gibbs Ensemble (GGE), but in experimental realizations dissipation often breaks integrability. In this work, w…
Dynamical probing of high-order spin coherence in one-dimensional mixtures
Silvia Musolino, Gianni Aupetit-Diallo, Mathias Albert +2
We investigate the dynamics of one-dimensional SU(2) ultracold fermions near the Tonks-Girardeau limit, confined in a box potential. The system is driven out of equilibrium by init…
