HIGHLIGHTS

• who: Generalized nonorthogonal matrix and colleagues from the Physical and Theoretical Chemistry Laboratory, Department of Chemistry, University of Oxford, South Parks Road, Oxford , QZ, United Kingdom have published the research work: Generalized nonorthogonal matrix elements: Unifying Wick’s theorem and the Slater-Condon rules, in the Journal: (JOURNAL)
• what: The authors show how evaluating intermediates for a given pair of determinants can reduce the scaling of overlap and one-body coupling terms between excited configurations to O(1).
