| Abstract: | Spatially-uniform light can induce topological properties in conventional insulators. I will demonstrate that spatial modulation of the radiating light allows remarkable control of the properties of these systems. I provide configurations which exhibit one-dimensional bulk modes, photo-induced currents, as well as fractionalized excitations. I show a close analogy to superconductors and use this analogy to explain these results. |
