Ground-state properties of a few-boson system in a one-dimensional hard-wall split potential
We carry out a detailed examination of the ground-state properties of a few-boson system in a one-dimensional hard-wall potential with a $\ensuremath{\delta}$ split in the center. In the Tonks-Girardeau limit with infinite repulsion between particles, we use the Bose-Fermi mapping to construct the exact $N$-particle ground-state wave function, which allows …
