Scaling behavior of Tan's contact for trapped Lieb-Liniger bosons: From two to many
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 1D 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 between our analytical results and DMRG calculations are …
