The momentum- and frequency-dependent correlation functions
(one-body and density-density) of the one-dimensional interacting Bose
gas are obtained for any value of the interaction parameter.
In the repulsive regime, we use the Algebraic Bethe Ansatz and the
recently developed ABACUS method to reconstruct the correlators to high
accuracy for systems with finite but large numbers of particles.
For attractive interactions, the correlations are computed analytically.
Our results are discussed, with particular emphasis on their
applications to quasi-one-dimensional atomic gases.(далее)
