Abstrakt

We present a method to apply the well-known matrix product state formalism to partially separable states in solid-state systems. The computational effort of our method is equal to the effort of the standard density matrix renormalization group (DMRG) algorithm. Consequently, it is applicable to all the usually considered condensed-matter systems where the DMRG algorithm is successful. We also show in exemplary cases that polymerization properties of ground states are closely connected to properties of partial separability, even if the ground state itself is not partially separable.
