Hello Jacob and Hello to Everyone
I read the "Chiral Quantum Walks" and this is so far what I coded:
Cannot get your plots, but close, please make sure the 'sites' are correct, for each variable in your paper I did some lines of code to understand it, self-explanatory in the file.
Symbolix are exactly your paper however ij needs to be i,j .
Basically I now understand what you were trying to do, but some detail is off to get exactly your plots.
I have no idea why you used Trotter expansion, since the exponentiaon has exact form, so I assume am missing a big point some place
