Dear all, There is some code dealing with Majorana fermions: "A.7 Majorana Fermion" on the paper "Kwant: a software package for quantum transport", by Christoph et al. I am still a novice and I'm not familiar with the physical system the code is written for. Neither do I understand why the onsite and hopping matrices are both 4*4 instead of 2*2 or something. May I know if there is some paper describing the model for this code, and why the onsite and hopping matrices are both 4*4? Thanks and regards, Tony
