Reply to "Comment on 'Generalization of the Kohn-Sham system that can represent arbitrary one-electron density matrices'"
Abstract
Our paper [Phys. Rev. A 93, 052512 (2016)], proposing a novel form of single determinant wave function that admits non-idempotent 1-electron density matrices, has recently received a Comment [Phys. Rev. A ??, 0????? (2017)] suggesting a number of flaws: The form of the 1-electron density matrix that we proposed is deemed invalid; None of the currently known functionals are given in terms of the 1-electron density matrix but known only in the basis where the density matrix is diagonal; In NOFT the energy is not invariant with respect to unitary transformations of the orbitals; The M\"uller functional we used suffers from serious shortcomings; In NOFT there detachment energies should be obtained from the extended Koopmans theorem. Below we will address these criticisms in sequence.
