Abstract
We extend previous work on applying the expansion to universal properties of a cold, dilute Fermi gas in the unitary regime of infinite scattering length. We compute the ratio of chemical potential to ideal gas Fermi energy to next-to-next-to-leading-order (NNLO) in , where is the number of spatial dimensions. We also explore the nature of corrections from the order after NNLO.
