Testing universality in ultracold fermion atomic gases

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.

Elastic interactions and complex patterns in binary systems

One of the many beauties of condensed matter physics is that it can reveal and illuminate how two systems or phenomena that at first appear ...
