Abstract

We extend previous work on applying the epsilon-expansion to universal\nproperties of a cold, dilute Fermi gas in the unitary regime of infinite\nscattering length. We compute the ratio xi = mu/epsilon_F of chemical potential\nto ideal gas Fermi energy to next-to-next-to-leading order (NNLO) in\nepsilon=4-d, where d is the number of spatial dimensions. We also explore the\nnature of corrections from the order after NNLO.\n
