Abstract
We present a systematic comparison of the most recent thermodynamic measurements of a trapped Fermi gas at unitarity with predictions from strong-coupling theories and quantum Monte Carlo (MC) simulations. The accuracy of the experimental data, of the order of a few percent, allows a precise test of different many-body approaches. We find that a Nozières and Schmitt-Rink treatment of fluctuations is in excellent agreement with the experimental data and available MC calculations at unitarity.
