Latent unified smooth Hamiltonians for excited state chemistry

David Juergens, Martin Stöhr, Andreas E. Hillers-Bendtsen +2

We describe a neural network architecture and training procedure designed to model electronic ground and excited states of arbitrary molecular systems. By indirectly learning a lat…

Accelerating CCSD(T) on Graphical Processing Units (GPUs)

O. Jonathan Fajen, Joseph E. Kelly, Edward G. Hohenstein +1

Coupled cluster with singles, doubles and perturbative triples (CCSD(T)) often provides ground state correlation energies within "chemical accuracy," but suffers from high computat…
