Today we had a nice colloquium by Chris Vale about recent experiments from his group testing Tan's universal relations for ultracold high density (k_F a much greater than 1) atomic Fermi gases with large scattering lengths a.
This regime corresponds to the centre of the figure below, taken from a Physics Today article by Carlos Sa de Melo
There is an interesting short Physics article by Eric Braaten which puts Tan's theory in a broader historical context.
