Momentum distribution of a freely expanding Lieb-Liniger gas
D. Jukić, B. Klajn, H. Buljan
We numerically study free expansion of a few Lieb-Liniger bosons, which are initially in the ground state of an infinitely deep hard-wall trap. Numerical calculation is carried out…

Free expansion of a Lieb-Liniger gas: Asymptotic form of the wave functions
D. Jukić, R. Pezer, T. Gasenzer +1
The asymptotic form of the wave functions describing a freely expanding Lieb-Liniger gas is derived by using a Fermi-Bose transformation for time-dependent states, and the stationa…
