Can a molecule's handedness create exotic quantum edge states?

Arrays of chiral molecules arranged in a zigzag-like pattern can host topological edge states — quantum modes pinned to the ends of a chain — where the left edge state lives on a left-handed molecule and the right on a right-handed one. This stereochemical labeling is unique to molecular chirality and has no equivalent in standard solid-state implementations. The framework applies to any dipolar molecule platform, from ultracold bialkali pairs to future chiral polyatomic arrays.
