A General Approach for Multireference Ground and Excited States using Non-Orthogonal Configuration Interaction

Hugh G. A. Burton, Alex J. W. Thom

A balanced description of ground and excited states is essential for the description of many chemical processes. However, few methods can handle cases where static correlation is p…

$P T$ -Symmetry in Hartree-Fock Theory

Hugh G. A. Burton, Alex J. W. Thom, Pierre-François Loos

$P T$ -symmetry --- invariance with respect to combined space reflection $P$ and time reversal $T$ --- provides a weaker condition than (Dirac) Hermitic…
