Python library for numerical quantum transport calculations

Kwant is a Python library for numerical calculations on tight-binding models with a strong focus on quantum transport. Kwant can be used to simulate a variety of systems and phenomena in quantum physics including: metals, graphene, topological insulators, quantum Hall effect, superconductivity, spintronics, molecular electronics, any combination of the above, and many other things. Kwant can calculate transport properties (conductance, noise, scattering matrix), dispersion relations, modes, wave functions, various Green’s functions, out-of-equilibrium local quantities.
