Algebraic Bethe ansatz approach to the correlation functions of the one-dimensional bosons with attraction
arXiv:2403.06882
Abstract
We consider a model of a one-dimensional Bose gas with attraction. We study ground state equal-time correlation functions in this model using the algebraic Bethe ansatz. In cases of strong interaction or/and large-volume systems, we obtain very simple explicit formulas for correlations.
