MC-DCFT is the most recently developed version of MC-NEFT. It is motivated by the relationship of the off-diagonal elements of the one-body reduced density matrix (1-RDM) to multiconfigurational effects in electronic wave functions, and it has an advantage of only using the 1-RDM in the nonclassical energy functional, which in the context of MC-DCFT is called the density coherence (DC) functional. In contrast, the two-body reduced density matrix (2-RDM) is needed in the nonclassical energy functional of MC-PDFT. The reason why one uses the 1-RDM is that it has a physical relation to the number of unpaired electrons, but we should keep in mind that the number of unpaired electrons is an interpretive quantity that has no unique definition, which will be an important consideration in the present work. The use of only the 1-RDM not only improves the physical interpretation and reduces the computational cost, but also it simplifies the development of the theory, making it easier to extend to more complex calculations. In the present article, we present a new functional form for the DC functional and parameterize a hybrid DC functional against the same database of bond dissociation energies and reaction barrier heights as used for our previous hybrid DC functional. The new functional will be called DC24. The new functional form improves both the accuracy and the physical interpretability of the functional.
