full name: tenpy.models.aklt
A simple implementation of the AKLT model.
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.
