Topological insulators in nanowire configurations enable control over their energy states through an external magnetic field. Numerical calculations of conductance using scattering matrix techniques reveal unique phenomena such as Van Hove singularities and weak antilocalization (WAL). Furthermore, these calculations allow us to observe the divergence of the localization length as a function of magnetic flux and the system's dimensions.
