Research

Jørgensen's list of peer-reviewed publications contains numerous self-contained articles which, in many cases, have become central sources within the field of electronic structure theory. His areas of research have been diverse and include work on: *multi-configurational self-consistent field (
MCSCF Multi-configurational self-consistent field (MCSCF) is a method in quantum chemistry used to generate qualitatively correct reference states of molecules in cases where Hartree–Fock and density functional theory are not adequate (e.g., for mole ...
) methods *Lagrangian techniques for molecular property calculations and analytic derivatives *time-independent and time-dependent linear and non-linear response function theory *
coupled cluster Coupled cluster (CC) is a numerical technique used for describing many-body systems. Its most common use is as one of several post-Hartree–Fock ab initio quantum chemistry methods in the field of computational chemistry, but it is also used in ...

Selected published works

Jørgensen has written more than 350 publications in peer-reviewed international journals, in addition to four books (3 co-authored and 1 edited), * * * * He had more than 19,000 citations and a h-index of 68 (according to ISI Web of Knowledge database). He has also organized the "Sostrup Summer School - Quantum Chemistry and Molecular Properties" alongside
