The thermodynamic properties of the Unitary Fermi Gas (UFG) have recently been measured to unprecedented accuracy by Ku et al. at the MIT. In particular, these measurements provide an improved understanding of the regime below T/eF ~ 0.20, where a transition into a superfluid phase occurs. In light of this new development, we present an overview of state-of-the-art Auxiliary Field Quantum Monte Carlo (AFQMC) results for the UFG at finite temperature, comparing with the MIT data for the energy, chemical potential and density. These AFQMC results have been obtained using methods based on the Hybrid Monte Carlo (HMC) algorithm, which was first introduced within the context of Lattice QCD.
