A one-shot GW calculation predicts that correlations remove the gamma hole pocket of La3Ni2O7 and that the La-5d x2-y2 band approaches the Fermi level under pressure and strain, matching ARPES without a Hubbard U.

Pressure and strain effects on the $\textit{ab initio}$ $GW$ electronic structure of La$_3$Ni$_2$O$_7$
A one-shot GW calculation predicts that correlations remove the gamma hole pocket of La3Ni2O7 and that the La-5d x2-y2 band approaches the Fermi level under pressure and strain, matching ARPES without a Hubbard U.
