Abstract
We establish an upper bound for the ground state energy per unit volume of a dilute Bose gas in the thermodynamic limit, capturing the correct second-order term, as predicted by the Lee–Huang–Yang formula. This result was first established in [20] by H.-T. Yau and J. Yin. Our proof, which applies to repulsive and compactly supported
$V \in L^3 (\mathbb {R}^3)$
, gives better rates and, in our opinion, is substantially simpler.
