  • Abstract The energy of the two-component Fermi gas with the s-wave contact interaction is a simple linear functional of its momentum distribution: E internal = ℏ 2 Ω C / 4 π am + ∑ k σ ( ℏ 2 k 2 / 2 m ) ( n k σ - C / k 4 ) where the external potential energy is not included, a is the scattering length, Ω is the volume, n k σ is the average number of fermions with wave vector k and spin σ , and C ≡ lim k → ∞ k 4 n k ↑ = lim k → ∞ k 4 n k ↓ . This result is a universal identity . Its proof is… CONTINUE READING
