Hi there, studying the Haldane model for my final year project next year, having some trouble understanding how the distant and nearest neighbour hopping works with varying width or height of a 2d sheet in the Haldane model? I'm find some references in papers but they appear to be way over my head and not accessible at all as I've only touched solid state physics (tight binding model and such) and not much condensed matter.
I'm also very interested to know how these hopping terms (NN or distant) are accounted for when looking at edge states in a bulk model?
I've also looked at how these edge states are calculated but I'm not having much luck. I assume it's something obvious and just the resulting energy spectrum from band theory and the tight binding model?
I would appreciate any kind of push in the correct direction, I've asked a lot of questions here but I'm a little scatter brained at the moment! I'll be doing a lot of reading over the weekend
