Hmm, sites in a 4x4 lattice is labeled like this:
``` (0,0) (0,1) (0,2) (0,3) (1,0) (1,1) (1,2) (1,3) (2,0) (2,1) (2,2) (2,3) (3,0) (3,1) (3,2) (3,3) ```
and (1, 1) and (1, 2) just means that two site in this lattice. it is the 5th and 6th dimension after flatten the lattice.
Maybe I should use something like A.slice({(1,1):1, (1,2):0}), I think.
Thank you very much
