SSH Chain: Topological Insulator (2D)

2D Su-Schrieffer-Heeger chain lab: drag the alternating hopping strengths to cross the trivial/topological phase transition and watch protected edge states light up, with a live bulk band-structure plot.

This 2D companion lays the same Su-Schrieffer-Heeger chain out flat: alternating bond thickness shows the intra-cell/inter-cell hopping ratio, atom glow shows the protected edge-state probability density, and a live E(k) plot below the chain shows the bulk gap opening and closing as you sweep through the topological phase transition.
