Closing the file f is optional and you can also write other objects to the same file before closing it. WebTo help with the logic of 2D lattices, ITensor pre-defines some helper functions which return an array of bonds. Each bond object has an "s1" field and an "s2" field which are the integers numbering the two sites the bond connects. (You can view the source for these functions at this link .)
