This project calculates quantum-level transport dynamics of a fully three-dimensional model Topolgoical Insulator (expandable and customizable to other materials in the Build_Hamiltonian file) channel in the Non-Equilibrium Green's Function Formalism. The code includes the capability to insert magnetic (both via Zeeman splitting and via a quantum phase brought about by the electromagnetic vector potential) and nonmagnetic disorder.  The code uses MPI to determine observables in a massively parallelized fashion, and uses a recursive Greens function routine to invert the block tridiagonal Hamiltonian at O(Npx*(Npy*Npz)^3) speed rather than O((Npx*Npy*Npz)^3).  The Math Kernel Library (MKL) is necessary to run this code.
