Quantum Corrections to the Ground State Energy Density of a Homogeneous Bose Gas
Quantum corrections to the properties of a homogeneous interacting Bose gas at zero temperature can be calculated as a low-density expansion in powers of scattering length. We calculate the ground state energy density to second order in $\sqrt{\rho a^3}$. The coefficient of the $\rho a^3$ correction...
