Dear Ian, There are 2 examples of superconducting systems in the tutorial (you have a link to download the code at the end). In Kwant paper, we have an example of Topological superconductor (the code is given in the appendix). Once you understand these examples you should be able to construct any system. Cheers, Xavier __________________________________________ Xavier Waintal SPSMS-INAC-CEA,17 rue des Martyrs, 38054 Grenoble CEDEX 9, FRANCE Tel: 33 (0)4 38 78 03 27 email: xavier.waintal@cea.fr http://inac.cea.fr/Pisp/xavier.waintal __________________________________________ Le 2 avr. 2014 à 19:58, Ian R George <iangeorge@utexas.edu> a écrit :

Hello,

I am an undergraduate student who is new to KWANT and condensed matter physics as a whole. I was wondering if anyone had some code meant to simulate the tight binding model for a topological insulator or superconductor, or could point me in the right direction? I have a paper that is helping me systematically construct the Hamiltonian analytically for different classes of TI's and TSC's, but I'm finding it hard to code. Maybe I just don't understand it well enough. I'm sorry if I'm stating something dumb or trivial.

Thank you for your time.
