Tan’s two-body contact across the superfluid transition of a planar Bose gas

Tan’s two-body contact across the superfluid transition of a planar Bose gas

Here the authors use Ramsey interferometry to study Tan’s contact in uniform two-dimensional Bose gas of 87Rb atoms across the Berezinskii–Kosterlitz–Thouless superfluid transition. They find that the two-body contact is continuous across the critical point.
