A generalization of the one-dimensional δ-function Bose gas

G. N. Ord, J. K. Percus

Research output: Contribution to journalArticlepeer-review


The one-dimensional boson gas with δ-function interaction is modified to include arbitrary pseudopotential interaction. The system is shown to be solvable by the Bethe Ansatz for certain classes of pseudopotential.
