kwant - A computer program for quantum transport — Anton Akhmerov1, Christoph Groth2, Xavier Waintal2, and •Michael Wimmer3 — 1Harvard University, USA — 2CEA Grenoble, France — 3Instituut-Lorentz, Universiteit Leiden, The Netherlands
We discuss methods for computing various quantum transport properties in tight-binding systems. We discuss both Green’s function and wave function based methods, and how to implement them in a numerically stable way. In addition, we also discuss practical issues such as convenient data structures for defining the transport problem in a computer program. These algorithms and data structures are implemented in an easy to use, open source python package - kwant.
