Exploring the accuracy of the equation-of-motion coupled-cluster band gap of solids
Evgeny Moerman, Henrique Miranda, Alejandro Gallo +7
While the periodic equation-of-motion coupled-cluster (EOM-CC) method promises systematic improvement of electronic band gap calculations in solids, its practical application at th…

RPA natural orbitals and their application to post-Hartree-Fock electronic structure methods
Benjamin Ramberger, Zoran Sukurma, Tobias Schäfer +1
We present a method to approximate post-Hartree-Fock correlation energies by using approximate natural orbitals obtained by the random phase approximation (RPA). We demonstrate the…
