Abstract

The ground state properties and low-lying excitations of a one-dimensional system of interacting bosons with open boundary conditions are studied. Haldane's harmonic-fluid description is generalized to this case. Ground state correlation functions are evaluated accounting for finite-size and boundary effects. The momentum distribution at small momenta is obtained from the one-particle density-matrix, and a method to extract the characteristic exponent from the experiment is proposed. A Bijl-Jastrow wave function for the ground state of this system is also derived.
