A simple implementation of the AKLT model.

Module description

Prototypical example of a 1D quantum model constructed from bond terms: the AKLT chain.

The AKLT model is famous for having a very simple ground state MPS of bond dimension 2. Writing down the Hamiltonian is easiest done in terms of bond couplings. This class thus serves as an example how this can be done in more gen The XXZ chain is contained in the more general SpinChain; the idea of this module is more to serve as a pedagogical example for a model.
