Abstract

We have analytically explored finite size and interparticle interaction corrections to the average energy of a harmonically trapped Fermi gas below and above the Fermi temperature, and have obtained a better fitting for the excess energy reported by DeMarco and Jin [Science 285, 1703 (1999)]. We have presented a perturbative calculation within a mean field approximation.
