Projected seniority-two orbital optimization of the Antisymmetric Product of one-reference orbital Geminal
Katharina Boguslawski, Paweł Tecmer, Peter A. Limacher +5
We present a new, non-variational orbital-optimization scheme for the Antisymmetric Product of one-reference orbital Geminal wave function. Our approach is motivated by the observa…
Longitudinal static optical properties of hydrogen chains: finite field extrapolations of matrix product state calculations
Sebastian Wouters, Peter A. Limacher, Dimitri Van Neck +1
We have implemented the sweep algorithm for the variational optimization of SU(2) x U(1) (spin and particle number) invariant matrix product states (MPS) for general spin and parti…
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…
