I saw some users mentioning Hall effect computations on the community, such as the program 'qhe.py'. But I couldn't find related code or tutorials. Hi, the program qhe.py is an example from the Kwant paper: https://kwant-project.org/doc/. You can find the source code in the

This should be enough to experiment with QHE. Note that the shown technique works only for constant field and all leads parallel to each other. If you need something more generic, see https://kwant-project.org/doc/1/pre/whatsnew/1.4#automatic-peierls-phase-cal....
If all you need are non-parallel leads withconstant field, a manual approach that uses a clever gauge transformation is also possible. I attach a quick-and-dirty example.
