Partition Function for a 1-D delta-function Bose Gas
arXiv:cond-mat/0212321 · doi:10.1103/PhysRevE.63.036106
Abstract
The N-particle partition function of a one-dimensional -function bose gas is calculated explicitly using only the periodic boundary condition (the Bethe ansatz equation). The N-particles cluster integrals are shown to be the same as those by the thermal Bethe ansatz method.
