Three-body local correlation function in the Lieb-Liniger model: bosonization approach
arXiv:cond-mat/0602468 · doi:10.1088/1742-5468/2006/08/P08015
Abstract
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].
