Third Order Upper Bound for the Ground State Energy of the Dilute Bose Gas

Year: 2026

Type: article

Abstract: We consider a dilute Bose gas in the thermodynamic limit. We prove an upper bound for the ground state energy per unit volume, capturing the expected third order term, as predicted by Wu, Hugenholtz-Pines and Sawada.
