Query: Exact Matrix Elements of the Field Operator in the Thermodynamic Limit
  of the Lieb-Liniger Model   We study a matrix element of the field operator in the Lieb-Liniger model
using the Bethe ansatz technique coupled with a functional approach to compute
Slavnov determinants. We obtain the matrix element exactly in the thermodynamic
limit for any coupling constant $c$, and compare our results to known
semiclassics at the limit $c\to0.$
