  We present results on the effect of short-range, attractive interactions on
the properties of balanced 2D Fermi gases in the non-superfluid (normal) phase.
Our approach combines the renormalization group (RG) with perturbation theory,
yielding observables such as the equation of state and compressibility. We find
good agreement with recent experiments that measured the equation of state in
trapped gases in the balanced regime, showing that these results are consistent
with logarithmic corrections in the equation of state.
