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…
