Hi,
Thanks for developing the ITensor. I used it for several months and find it is really easy to learn and program even through I am not familiar with Julia at the very beginning.
I find that ITensor currently only supports Abelian symmetry group, whose quantum number, as a fusion category, is pointed. Just want to know, whether developers are planning to add the non-Abelian group symmetry in the future. Since non-Abelian symmetry is perhaps much more complicated than the Abelian case since it has fusion multiplicities and non-trivial F-symbols. The storage and decompositions are complicated.
If I want to modify the ITensor program to include non-Abelian symmetry in my calculation, where should I start?
