@Jonas_schwab it seems to me that some allocate statements are not always followed by deallocations. Is there also an issue with CT(mat) vs. conjg(transpose(mat))?

The missing deallocate statements are mainly laziness on my part. It's a bit unclean, but the compiler should free the space at the end of the respective scopes. If we want merge this, we should probably clean that up. But in this case, there would also be some more to do, e.g. adapt subroutine Obser for all Hamiltionians.

The function CT also suffers from segfaults without -heap-arrays.
