We have implemented the sweep algorithm for the variational optimization ofSU(2) x U(1) (spin and particle number) invariant matrix product states (MPS)for general spin and particle number invariant fermionic Hamiltonians. Thisclass includes non-relativistic quantum chemical systems within theBorn-Oppenheimer approximation. High-accuracy ab-initio finite field results ofthe longitudinal static polarizabilities and second hyperpolarizabilities ofone-dimensional hydrogen chains are presented. This allows to assess theperformance of other quantum chemical methods. For small basis sets, MPScalculations in the saturation regime of the optical response properties can beperformed. These results are extrapolated to the thermodynamic limit.
