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.

An ambitious interactive physics repository exploring quantum tunneling from textbook wave-packet barrier penetration to tunneling time, relativistic Klein tunneling, false-vacuum decay, and Hawking radiation, combining live browser simulation with research-quality Python validation.
