Recurrence time in the quantum dynamics of the 1D Bose gas
Eriko Kaminishi, Jun Sato, Tetsuo Deguchi
Recurrence time is evaluated for some initial quantum states in the one-dimensional Bose gas with repulsive short-range interactions. In the relatively strong and weak coupling cas…

Finite-size scaling behavior of Bose-Einstein condensation in the 1D Bose gas
Jun Sato, Eriko Kaminishi, Tetsuo Deguchi
Through exact numerical solutions we show Bose-Einstein condensation (BEC) for the one-dimensional (1D) bosons with repulsive short-range interactions at zero temperature by taking…
