Computing Exchange Coupling constants in Transition metal complexes with Tensor Product Selected Configuration Interaction
Arnab Bachhar, Nicholas J. Mayhall
Transition metal complexes present significant challenges for electronic structure theory due to strong electron correlation arising from partially filled -orbitals. We compare…

Restricted Open-shell cluster Mean-Field theory for Strongly Correlated Systems
Arnab Bachhar, Nicholas J. Mayhall
The cluster-based Mean Field method (cMF) and it's second order perturbative correction[1], was introduced by Jiménez-Hoyos and Scuseria to reduce the cost of modeling strongly cor…

Accurate and Interpretable Representation of Correlated Electronic Structure via Tensor Product Selected CI
Nicole M. Braunscheidel, Arnab Bachhar, Nicholas J. Mayhall
The task of computing wavefunctions that are accurate, yet simple enough mathematical objects to use for reasoning has long been a challenge in quantum chemistry. The difficulty in…
