Index

)

Generates a chain of SU(3) spins.

Parameters

length

length of the chain

The single local basis state is a one-dimensional state of the fundamental IREP (1,0) of SU(3).

Two local operators are generated, pl and pr. Unfortunately, multiplying the operators together directly does not yield the exchange term $\hat P_{ij} |\alpha_i \beta_j\rangle = |\beta_i \alpha_j\rangle$. To build this term, start with an identity and replace the tensors on neighbouring sites by the active site tensors of pl and pr respectively.
