Dynamics of trapped one-dimensional bosons for intermediate repulsive interactions
The time-evolution of few number of interacting, harmonically confined one-dimensional bosons is numerically obtained for arbitrary two-body $\delta-$potential interaction strengths. It is demonstrated that the period of the motion in a Newton's cradle configuration undergoes two crossovers as...

Summary: | The time-evolution of few number of interacting, harmonically confined
one-dimensional bosons is numerically obtained for arbitrary two-body
$\delta-$potential interaction strengths. It is demonstrated that the period of
the motion in a Newton's cradle configuration undergoes two crossovers as a
function of interactions. Furthermore, through the evaluation of the structure
factor, the dependence of Bragg-scattering peaks on the interaction strength
ranging from the weak coupling regime to the impenetrable Tonks-Girardeau case
is illustrated. |
