We use and extend recently developed techniques to give a rigorous derivation of the asymptotic formula for the ground-state energy of a dilute gas of N fermions interacting with a short-range, positive potential of scattering length a. For spin-12 fermions, this is E∼E0+(22m)2πNa, where E0 is the energy of the noninteracting system and is the density. A similar formula holds in two dimensions (2D), with a replaced by ln(a2). Obviously this 2D energy is not the expectation value of a density-independent pseudopotential."}],"quality_controlled":0,"publisher":"American Physical Society","issue":"5","publist_id":"4565","intvolume":"        71","volume":71,"_id":"2362","doi":"10.1103/PhysRevA.71.053605","title":"Ground state energy of the low density Fermi gas","date_updated":"2021-01-12T06:57:01Z","author":[{"first_name":"Élliott","last_name":"Lieb","full_name":"Lieb, Élliott H"},{"id":"4AFD0470-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6781-0521","full_name":"Robert Seiringer","last_name":"Seiringer","first_name":"Robert"},{"full_name":"Solovej, Jan P","last_name":"Solovej","first_name":"Jan"}],"month":"05","type":"journal_article","citation":{"apa":"Lieb, É., Seiringer, R., &#38; Solovej, J.
