Electron affinities with GPU-accelerated density-fitting EOM-CCSD, approximate EOM-CCSD methods and EOM-CCSD with frozen natural orbitals.

This work employs multiple strategies to reduce computational cost or increase computational efficiency in calculating electron affinities (EAs) based on the equation-of-motion coupled-cluster singles and doubles (EOMEA-CCSD) method. To reduce storag…
