A Transcorrelated Wave-Function Framework for Solids: An Application to Bulk and Defected Silicon
Kristoffer Simula, Johannes Hauskrecht, Evelin Martine Corvid Christlmaier +4
Accurate wave-function descriptions of pristine and defected solids remain challenging due to the simultaneous presence of finite-size, basis-set, and correlation errors. While emb…

Transcorrelated Theory for Transition Metal Atoms
Kristoffer Simula, Maria-Andreea Filip, Ali Alavi
We benchmark ionisation and excitation energies of transition-metal atoms Sc-Zn with a transcorrelated Hamiltonian combined with pseudopotentials. The similarity transformed Hamilt…
