Freespace “twistronics”: moiré structured light for optical supertopologies

Moiré superlattices of twisted bilayer 2D materials creating nontrivial physical effects have recently revolutionized diverse subjects across materials, optoelectronics, nanophotonics, and beyond. Here, we present moiré superlattices in higher-dimensional freespace optics, where...
