High-accuracy ab-initio quantum chemistry by means of an SU(2) x U(1) invariant matrix product state Ansatz: the static second hyperpolarizability
Sebastian Wouters, Peter A. Limacher, Dimitri Van Neck +1
We have implemented the single-site density matrix renormalization group algorithm for the variational optimization of SU(2) \times U(1) (spin and particle number) invariant matrix…

Exact Ionization Potentials from Wavefunction Asymptotics: The Extended Koopmans' Theorem, Revisited
Diederik Vanfleteren, Dimitri Van Neck, Paul W. Ayers +2
A simple explanation is given for the exactness of the extended Koopmans' theorem for computing the removal energy of any many-electron system to the lowest-energy ground state ion…
