Scaling behavior of Tan's contact for trapped Lieb-Liniger bosons : from two to many

We show that the contact parameter of N harmonically trapped interacting one-dimensional bosons at zero temperature can be analytically and accurately obtained by a simple rescaling of the exact two-boson solution, and that N-body effects can be almost factorized. The small deviations observed betwe...
