A simple 2nd order lower bound to the energy of dilute bose gases
For a dilute system of non-relativistic bosons interacting through a positive, radial potential v with scattering length a we prove that the ground state energy density satisfies the bound $$e(\rho ) \ge 4\pi a \rho ^2 (1- C \sqrt{\rho a^3} \,)$$e(ρ)≥4πaρ2(1-Cρa3).
