- Hi all,
I got a question regarding only perform the calculation for position operators and overlap matrices. Given you have a very large system, like TBG. Sparse calculation is needed. In the "truncation.c", the OLP and H0 is already being calculated. However, I also need the position operator.
I know how to only obtain the overlap matrices (by modified the truncation.c and opnmx.c), but is it possible to extract the position operators as well? If yes, how can I do it?
Best, Angus Hsu (Ph.D. students @ northeastern university)
