Third order corrections to the ground state energy of a Bose gas in the Gross-Pitaevskii regime

Cristina Caraci, Alessandro Olgiati, Diane Saint Aubin +1

For a translation invariant system of $N$ bosons in the Gross-Pitaevskii regime, we establish a precise bound for the ground state energy $E_N$. While the leading, order $N$, contr…
