The Tan's contact is related to two-body interactions in
quantum gases with short-range interactions. It is an ubiquitous
quantity, determining eg the interaction energy, the two-body
correlation function at zero distance, the tails of the momentum
distribution and the rf-spectroscopy tails. I will present our
results for the Tan's contact of strongly interacting bosons and
fermions in a tight atomic waveguide, highlighting its universal
aspects, its temperature dependence and the possibility to use it to
extract the symmetry properties of a quantum mixture.
