We compute the ground state energy for a system of 6, 10, 14, 18, and 22 particles, with equal numbers of up and down spins in a periodic cube. We estimate that in the limit of large number of particles, the ground state energy is 0.25(3) times the ground state energy of the free Fermi system.", "revisions": [ { "version": "v2", "updated": "2006-01-06T14:21:24.000Z" } ], "analyses": { "keywords": [ "ground state energy", "unitary limit", "free fermi system", "fermion system", "lattice results" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
