Three-body local correlation function in the Lieb-Liniger model: bosonization approach


Abstract in English

We develop a method for the calculation of 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 [1].
