I want to study electronic and thermal transport properties of a Weyl semimetal. Until now, I have used only the continuum model hamiltonian ($H=k⋅σ$). As the continuum model has several limitations, a lattice model would potentially be an improvement. But, more realistic studies could be done with tight binding analysis. However, as a beginner, I don't know how to implement a Weyl semimetal in a tight binding model.

I have seen several example of tight binding codes to implement Graphene and other 2D topological materials using kwant, but didn't find any example for a Weyl semimetal.

Is there any example codes written by others (ideally in Python)? Are there any dedicated Python packages (other than kwant) to handle it?
