Generating Matrix Product States from a (random) vector
I try to decomposite an arbitrary quantum state into a matrix product state. For this i follow this paper by U. Schollwöck where especially section 4.1.3 is relevant.
So far I did the following:

Is there any study about using DMRG to simulate two spin chains coupled at only several sites on each chain?
Is there any study about the DMRG simulation of such kind of systems?
or
Each blue site is a spin, for example. Only one or several spins on each chain are coupled.

How to compute the MPS representation for a sequence of asymptotically gapped quantum spin chains
Suppose I have a sequence of gapped, spin-$1/2$, translationally invariant quantum spin chains $\{H_1, H_2,H_3\cdots\}$ with interactions of range $\leq 2$ (i.e. no further than nearest-neighbors).
