Hi all! Now I want to calculate a Hamiltonian defined by myself, by using ITensor.jl.
This Hamiltonian is a SU(3) spin model, here I need to construct a Hamiltonian by 8 Gell-Mann matrices, and then to use MPS/MPO to write it. I have sucessfully written it and calculated out some useful results.
Now I want to consider some excited states, and it would be more efficient if adding some symmetry (in fact, the model conserves SU(3) symmetry). How should I do?
