WannierTools: An open-source software package for novel topological materials. Full documentation:

A package for quickly constructing k·p models of magnetic and non-magnetic crystals

Python package for time-dependent wave-packet transport in 2D Dirac and Weyl systems. Supports tilted, anisotropic cones, arbitrary barrier geometries, valley chirality, and intervalley coupling via a split-operator Fourier scheme on a uniform grid.
