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 <InlineEquation ID="IEq1"> <EquationSource Format="TEX"> $\sqrt {\rho a^3 }$ </EquationSource> </InlineEquation>, where ρ is the number density and a is the S-wave scattering length. We calculate the ground state energy density to...</equationsource></inlineequation>
