摘要：
We develop a method to calculate vacuum expectation values of local operators in the Lieb-Liniger model. This method is based on a set of new identities obtained using integrability and effective theory ('bosonization') description. We use this method to get an explicit expression for the three-body local correlation function, measured in a recent experiment.
