    "abstract": "We study cold dilute neutron matter on the lattice using an effective field\ntheory. We work in the unitary limit in which the scattering length is much\nlarger than the interparticle spacing. In this paper we focus on the equation\nof state at temperatures above the Fermi temperature and compare lattice\nsimulations to the virial expansion on the lattice and in the continuum. We\nfind that in the unitary limit lattice discretization errors in the second\nvirial coefficient are significantly enhanced. As a consequence the equation of\nstate does not show the universal scaling behavior expected in the unitary\nlimit. We suggest that scaling can be improved by tuning the second virial\ncoefficient rather than the scattering length.",
