Query: Recurrence times of the Lieb-Liniger model in the weak and strong
  coupling regimes   Quantum systems exhibit recurrence phenomena after equilibration, but it is a
difficult task to evaluate the recurrence time of a quantum system because it
drastically increases as the system size increases (usually double-exponential
in the number of particles) and strongly depends on the initial state. Here, we
analytically derive the recurrence times of the Lieb-Liniger model with
relatively small particle numbers for the weak and strong coupling regimes. It
turns out that these recurrence times are independent of the initial state and
increases only polynomially in the system size.
