Exciting temporal oscillations of the density distribution is a high-precision method for
probing ultracold trapped atomic gases. Interaction effects in their many-body dynamics are …

We study one-dimensional (1D) strongly interacting Bose–Fermi mixtures by both the exact
Bethe-ansatz method and variational perturbation theory within the degenerate ground state …

We show that the wave function in one spatial sector x 1< x 2<⋯< x N (with xi being the
coordinate of the i th particle) of a one-dimensional spinor gas with contact s-wave …

Quantum many-body systems in one dimension (1D) exhibit some peculiar properties. In this
article, we review some of our work on strongly interacting 1D spinor quantum gas. First, we …

In this article, we consider the monopole excitations of a harmonically trapped Bose gas in
the vicinity of the Tonks-Girardeau limit. Using Girardeau's Fermi-Bose duality and …

We analyze interacting one-dimensional bosons in the continuum, subject to a periodic
sinusoidal potential of arbitrary depth. Variation of the lattice depth tunes the system from the …

A study of breathing oscillations of a one-dimensional trapped interacting Bose gas is
presented. Oscillations are initiated by an instantaneous change of the trapping frequency …

We have investigated quantum entanglement for two interacting ultracold bosonic atoms in
one-dimensional harmonic traps. The effective potential is modeled by delta interaction. For …

Nonequilibrium quantum physics is of fundamental importance and interest. It is still an
extremely hard issue even in today's theoretical physics because of the lack of the …

3ωz) regimes. Predictions from local density and Hartree approximations can be
continuously matched for N>∼ 25 particles, providing a complete zero-temperature …
