Cluster coefficients for the one-dimensional Bose gas with point interactions
L. R. Dodd, Anne-Marie Gibbs
Exact expressions for the cluster coefficients b2 and b3 for the one-dimensional Bose gas with repulsive δ-function interactions are found. The calculation depends only on scattering information in the form of two- and three-body scattering wavefunctions. Although not in agreement with a previous calculation by Servadio, our results are shown to be consistent with the work of Yang and Yang which involves the use of periodic rather than scattering boundary conditions.
