The ground state energy of one-dimensional two-component Fermi gas with the attractive δ-function interaction is fitted with a simple approximate function.

Yahui Wang, Zhong-Qi Ma

In terms of the Thomas–Fermi method, we solve the ground state energy of the N-body 1D harmonically trapped spin-1/2 fermion gas with the attractive δ-function interaction in the limit N → ∞ .
