Local correlations reveal the superfluid to normal boundary in a trapped two-dimensional quantum gas

This paper reports the model free determination of the two-fluid dynamics in a trapped two-dimensional Bose gas, relying on a local principal component analysis of the dynamics after a sudden excitation.
