Excitation Operators

Excitation Operators is a formal quantum mechanical construct in electronic structure theory that generates excited Slater determinants from a reference wavefunction by promoting electrons from occupied to virtual orbitals, thereby enabling the systematic improvement of the wavefunction in configuration interaction methods.
