Molecular Structure Extraction From Documents Using Deep Learning
Joshua Staker, Kyle Marshall, Robert Abel +1
Chemical structure extraction from documents remains a hard problem due to both false positive identification of structures during segmentation and errors in the predicted structur…

Excitation spectra from angular momentum projection of Hartree-Fock states and the configuration-interaction shell-model
Joshua T. Staker, Calvin W. Johnson
We make numerical comparison of spectra from angular-momentum projection on Hartree-Fock states with spectra from configuration-interaction nuclear shell-model calculations, all ca…

Many-body approximations for atomic binding energies
Micah D. Schuster, Calvin W. Johnson, Joshua T. Staker
We benchmark three standard approximations for the many-body problem -- the Hartree-Fock, projected Hartree-Fock, and random phase approximations -- against full numerical configur…
