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…
Fermi-Bose transformation for the time-dependent Lieb-Liniger gas
H. Buljan, R. Pezer, T. Gasenzer
Exact solutions of the Schrodinger equation describing a freely expanding Lieb-Liniger (LL) gas of delta-interacting bosons in one spatial dimension are constructed. The many-body…
The single-particle density matrix and the momentum distribution of dark "solitons" in a Tonks-Girardeau gas
H. Buljan, K. Lelas, R. Pezer +1
We study the reduced single-particle density matrix (RSPDM), the momentum distribution, natural orbitals and their occupancies, of dark "soliton" (DS) states in a Tonks-Girardeau g…
Dark stationary matter-waves via parity-selective evaporation in a Tonks-Girardeau gas
H. Buljan, O. Manela, R. Pezer +2
We propose a scheme for observing dark stationary waves in a Tonks-Girardeau (TG) gas. The scheme is based on parity-selective dynamical "evaporation" of the gas via a time-depende…
Incoherent matter-wave solitons
H. Buljan, M. Segev, A. Vardi
The dynamics of matter-wave solitons in Bose-Einstein condensates (BEC) is considerably affected by the presence of a surrounding thermal cloud and by condensate depletion during i…
